    Yeah, not sure the conclusion of the article really matches the data.

    Students were invited to talk to an AI. They did so, and having done so they expressed a clear preference for written exams - which can be taken under exam conditions to prevent cheating, something universities have hundreds of years of experience doing.

    I know some universities started using the square wheel of online assessment during covid and I can see how this octagonal wheel seems good if you've only ever seen a square wheel. But they'd be even better off with a circular wheel, which really doesn't need re-inventing.

      That's what so surprising to me - they data clearly shows the experiment had terrible results. And the write up is nothing but the author stating: "glowing success!".

      And they didn't even bother to test the most important thing. Were the LLM evaluations even accurate! Have graders manually evaluate them and see if the LLMs were even close or were wildly off.

      This is clearly someone who had a conclusion to promote regardless of what the data was going to show.

      The quote you gave is not the conclusion of the article. It's a self-evident claim that just as well could have been the first sentence of the article ("take-home exams are dead"), followed by an opinion ("reverting ... feels like a regression") which motivated the experiment.

      Some universities and professors have tried to move to a take-home exam format, which allows for more comprehensive evaluation with easier logistics than a too-brief in-class exam or an hours-long outside-of-class sitting where unreasonable expectations for mental and sometimes physical stamina are factors. That "take-home exams are dead" is self-evident, not a result of the experiment in the article. There used to be only a limited number of ways to cheat at a take-home exam, and most of them involved finding a second person who also lacked a moral conscience. Now, it's trivial to cheat at a take-home exam all by yourself.

      You also mentioned the hundreds of years of experience universities have at traditional written exams. But the type and manner of knowledge and skills that must be tested for vary dramatically by discipline, and the discipline in question (computer science / software engineering) is still new enough that we can't really say we've matured the art of examining for it.

      Lastly, I'll just say that student preference is hardly the way to measure the quality of an exam, or much of anything about education.

      One student had to talk to an AI for more than 60 minutes. These guys are creating a dystopia. Also students will just have an AI pick up the phone if this gets used for more than 2 semesters.

      The issue is that it is not scalable, unless there is some dependable, automated way to convert handwriting to text.

        Why is this a problem now, but was not a problem for the past few centuries? This class had 36 students, you could grade that in a single evening.

          I agree with you and the other posters actually, but I think the efficiency compared with typed work is the reason it’s having such a slow adoption. Another thing to remember is that there is always a mild Jevons paradox at play; while it's true that it was possible in previous centuries, teacher expectations have also increased which strains the amount of time they would have grading handwritten work.
      • pgalvin 1 hour ago
        University exams being marked by hand, by someone experienced enough to work outside a rigid marking scheme, has been the standard for hundreds of years and has proven scalable enough. If there are so many students that academics can’t keep up, there are likely too many students to maintain a high standard of education anyway.

          > there are likely too many students to maintain a high standard of education anyway.

          Right on point. I find particularly striking how little is said about whether the best students achieve the best grades. Authors are even candid that different LLMs asses differently, but seem to conclude that LLMs converging after a few rounds of cross reviews indicate they are plausible so who cares. The apparences are safe.

        When college degrees cost as much as they do, it's reasonable to pay people to do the transcription and/or grading.

        Work study and TA jobs were abundant when I was in college. It wasn't a problem in the past and shouldn't be a problem now.

        I assure you, oral exams are completely scalable. But it does require most of a university's budget to go towards labs and faculty, and not administration and sports arenas and social services and vanity projects and three-star dorms.

          One way of scaling out interactive/oral assessment (and personalized instruction in general) is to hire a group of course assistants/tutors from the previous cohort.
  • lifetimerubyist 2 hours ago
    This is all so crazy to me.

    I went to school long before LLMs were even a Google Engineer's brianfart for the transformer paper and the way I took exams was already AI proof.

    Everything hand written in pen in a proctored gymnasium. No open books. No computers or smart phones, especially ones connected to the internet. Just a department sanctioned calculator for math classes.

    I wrote assembly and C++ code by hand, and it was expected to compile. No, I never got a chance to try to compile it myself before submitting it for grading. I had three hours to do the exam. Full stop. If there was a whiff of cheating, you were expelled. Do not pass go. Do not collect $200.

    Cohorts for programs with a thousand initial students had less than 10 graduates. This was the norm.

    You were expected to learn the gd material. The university thanks you for your donation.

    I feel like i'm taking crazy pills when I read things about trying to "adapt" to AI. We already had the solution.

      I basically agree with the thrust of what you're saying, but also:

      > I wrote assembly and C++ code by hand, and it was expected to compile. No, I never got a chance to try to compile it myself before submitting it for grading.

      Do you, like, really think this is the best way to assess someone's ability? Can't we find a place between the two extremes?

      Personally, I'd go with a school-provided computer with a development environment and access to documentation. No LLMs, except maybe (but probably not) for very high-level courses.

        The safe middle space still does not involve a computer

        Lots of my tests involved writing pseudocode, or "Just write something that looks like C or Java". Don't miss the semicolon at the end of the line, but if you write "System.print()" rather than "System.out.printLn()" you might lose a single point. Maybe.

        If there were specific functions you need to call, it would have a man page or similar on the test itself, or it would be the actual topic under test.

        I hand wrote a bunch of SQL queries. Hand wrote code for my Systems Programming class that involved pointers. I'm not even good with pointers. I hand wrote Java for job interviews.

        It's pretty rare that you need to actually test someone can memorize syntax, that's like the entire point of modern development environments.

        But if you are completely unable to function without one, you might not know as much as you would hope.

        The first algorithms came before the first programming languages.

        Sure, it means you need to be able to run the code in your head and be able to mentally "debug" it, but that's a feature

        If you could not manage these things, you washed out in the CS101 class that nearly every STEM student took. The remaining students were not brilliant, but most of them could write code to solve problems. Then you got classes that could actually teach and test that problem solving itself.

        The one class where we built larger apps more akin to actual jobs, that could have been done entirely in the lab with locked down computers if need be, but the professor really didn't care if you wanted to fake the lab work, you still needed to pass the book learning for "Programming Patterns" which people really struggled with and you still needed to be able to give a "Demo" and presentation, and you still needed to demonstrate that you understood how to read some requests from a "Customer" and turn it into features and requirements and UX

        Nobody cares about people sabotaging their own education except in programming because no matter how much MBAs insist that all workers are replaceable, they cannot figure out a way to actually evaluate the competency of a programmer without knowing programming. If an engineer doesn't actually understand how to evaluate static stresses on a structure, they are going to have a hard time keeping a job. Meanwhile in the world of programming, hopping around once a year is "normal" somehow, so you can make a lot of money while literally not knowing fizzbuzz. I don't think the problem is actually education.

        Computer Science isn't actually about using a laptop.

      And why is this a flex exactly? Almost sounds like fraud. Get sold on how you'll be taught well and become successful. Pay. Then be sent through an experience that filters so severely, only 1% of people pass. Receive 100% of the blame when you inevitably fail. Repeat for the other 990 students. The "university thanks you for your donation" slogan doesn't sound too hot all of a sudden.

      It's like some malicious compliance take on both teaching and studying. Which shouldn't even be surprising, considering the circumstances of the professors e.g. where I studied, as well as the students'.

      Mind you, I was (for some classes) tested the same way. People still cheated, and grading stringency varied. People still also forgot everything shortly after wrapping up their finals on the given subjects and moved on. People also memorized questions and compiled a solutions book, and then handed them down to next year's class. Because this method does jack against that on its own. You still need to keep crafting novel questions, vary them more than just by swapping key values, etc.

        Do you think you're just purchasing a diploma? Or do you think you're purchasing the opportunity to gain an education and potential certification that you received said education?

        It's entirely possible that the University stunk at teaching 99% of it's students (about as equally possible that 99% of the students stunk at learning), but "fraud" is absolute nonsense. You're not entitled to a diploma if you fail to learn the material well enough to earn it.

      I've had colleagues argue (prior to LLMs) that oral exams are superior to paper exams, for diagnosing understanding. I don't know how to validate that statement, but if the assumption is true than there is merit to finding a way to scale them. Not saying this is it, but I wouldn't say that it's fair to just dismiss oral exams entirely.
      • NewsaHackO 1 hour ago
        Yes, I hate oral exams, but they are definitely better at getting a whole picture of a person's understanding of topics. A lot of specialty boards in medicine do this. To me, the two issues are that it requires an experienced, knowledgeable, and empathetic examiner, who is able to probe the examinee about areas they seem to be struggling in, and paradoxically, its strength is in the fact that it is subjective. The examiner may have set questions, but how the examinee answers the questions and the follow-up questions are what differentiate it from a written exam. If the examiner is just the equivalent of a customer service representative and is strictly following a tree of questions, it loses its value.

      TFA's case involved examinations about the student's submitted project work. It's not the same thing. Even for a more traditional examination with no such context attached one might still want to rely on AI for grading. (Yeah, I know, that comes across as "the students are not allowed to use AI for cheating, but the profs are!".)

      Also, IMO oral examinations are quite powerful for detecting who is prepared and who isn't. On the down side they also help the extroverts and the confident, and you have to be careful about preventing a bias towards those.

        > On the down side they also help the extroverts and the confident, and you have to be careful about preventing a bias towards those.

        This is true, but it is also why it is important to get an actual expert to proctor the exam. Having confidence is good and should be a plus, but if you are confident about a point that the examiner knows is completely incorrect, you may possibly put yourself in an inescapable hole, as it will be very difficult to ascertain that you actually know the other parts you were confident (much less unconfident) in.

      • jimbokun 58 minutes ago
        You could argue that for fields like law, medicine and management extroversion and confidence are important qualities.

    > We love you FakeFoster, but GenZ is not ready for you.

    Don't tell me about GenZ. I had oral exams in calculus as undergrad, and our professor was intimidating. I barely passed each time when I got him as examiner, though I did reasonably well when dealing with his assistant. I could normally keep my emotions in check, but not with my professor. Though, maybe in that case the trigger was not just the tone of professor, but the sheer difference in the tone he used normally (very friendly) and at the exam time. It was absolutely unexpected at my first exam, and the repeated exposure to it didn't help. I'd say it was becoming worse with each time. Today I'd overcome such issues easily, I know some techniques today, but I didn't when I was green.

    OTOH I wonder, if an AI could have such an effect on me. I can't treat AI as a human being, even if I wanted to, it is just a shitty program. I can curse a compiler refusing to accept a perfectly valid borrow of a value, so I can curse an AI making my life difficult. Mostly I have another emotional issue with AI: I tend to become impatient and even angry at AI for every small mistake it does, but this one I could overcome easily.

      In Italy, every exam has an oral component, from elementary school all the way to university. I perform horribly under such condition, my mind goes blank entirely.

      I wish that wasn't a thing.

      Interviews are similar, but different: I'm presenting myself.

  • semilin 31 minutes ago
    This seems like a mistake. On the one hand, other commenters' experiences provide additional evidence that oral communication is a vastly different skill from the written word and ought to be emphasized more in education. Even if a student truly understands a concept, they might struggle at talking about it in a realtime context. For many real-world cases, this is unacceptable. Therefore the skill needs to be taught.

    On the other hand, can an AI exam really simulate the conditions necessary for improving at this skill? I think this is unlikely. The students' responses indicate not a general lack of expertise in oral communication but also a discomfort with this particular environment. While the author is making steps to improve the environment, I think it is fundamentally too different from actual human-to-human discussion to test a student's ability in oral communication. Even if a student could learn to succeed in this environment, it won't produce much improvement in their real world ability.

    But maybe that's not the goal, and it's simply to test understanding. Well, as other commenters have stated, this seems trivially cheatable. So it neither succeeds at improving one's ability in oral communication nor at testing understanding. Other solutions have to be thought of.

  • phren0logy 16 minutes ago
    I had plenty of oral exams throughout my education and training. It's interesting to see their resurgence, and easy to understand the appeal. If they can be done rigorously and fairly (no easy thing), then they go much further than multiple can in demonstrating understanding of concepts. But, they are inherently more stressful. I agree with the article that the increased pressure is a feature, not a bug. It's much more real-world for many kinds of knowledge.

    > Many students who had submitted thoughtful, well-structured work could not explain basic choices in their own submission after two follow-up questions.

    When I was doing a lot of hiring we offered the option (don’t roast me, it was an alternative they could choose if they wanted) of a take-home problem they could do on their own. It was reasonably short, like the kind of problem an experienced developer could do in 10-15 minutes and then add some polish, documentation, and submit it in under an hour.

    Even though I told candidates that we’d discuss their submission as part of the next step, we would still get candidates submitting solutions that seemed entirely foreign to them a day later. This was on the cusp of LLMs being useful, so I think a lot of solutions were coming from people’s friends or copied from something on the internet without much thought.

    Now that LLMs are both useful and well known, the temptation to cheat with them is huge. For various reasons I think students and applicants see using LLMs as not-cheating in the same situations where they wouldn’t feel comfortable copying answers from a friend. The idea is that the LLM is an available tool and therefore they should be able to use it. The obvious problem with that argument is that we’re not testing students or applicants on their abilities to use an LLM, we’re using synthetic problems to explore their own skills and communication.

    Even some of the hiring managers I know who went all in on allowing LLMs during interviews are changing course now. The LLM-assisted interviewed were just turning into an exercise of how familiar the candidate was with the LLM being used.

    I don’t really agree with some of the techniques they’re using in this article, but the problem they’re facing is very real.

    At the price per student it probably makes sense to run some voluntary trial exams during the semester. This would give students a chance to get acquainted to the format, help them check their understanding and if the voice is very intimidating allow them to get used to that as well.

    As an aside, I'm surprised oral exams aren't possible at 36 students. I feel like I've taken plenty of courses with more participants and oral exams. But the break even point is probably very different from country to country.

      >As an aside, I'm surprised oral exams aren't possible at 36 students.

      It depends on how frequent and how in-depth you want the exams to be. How much knowledge can you test in an oral exam that would be similar to a two-hour written exam? (Especially when I remember my own experience where I would have to sketch ideas for 3/4th of the time alloted before spending the last 1/4th writing frenetically the answer I found _in extremis_).

      If I were a teacher, my experience would be to sample the students. Maybe bias the sample towards students who give wrong answers, but then it could start either a good feedback loop ("I'll study because I don't want to be interrogated again in front of the class") or a bad feedback loop ("I am being picked on, it is getting worse than I can improve, I hate this and I give up")

      Turns out that under the USA Code of Federal Regulations, there's a pretty big exemption to IRB for research on pedagogy:

      CFR 46.104 (Exempt Research):

      46.104.d.1 "Research, conducted in established or commonly accepted educational settings, that specifically involves normal educational practices that are not likely to adversely impact students' opportunity to learn required educational content or the assessment of educators who provide instruction. This includes most research on regular and special education instructional strategies, and research on the effectiveness of or the comparison among instructional techniques, curricula, or classroom management methods."

    Reminder: This professor's school costs $90k a year, with over $200k total cost to get an MBA. If that tuition isn't going down because the professor cut corners to do an oral exam of ~35 students for literally less than a dollar each, then this is nothing more than a professor valuing getting to slack off higher than they value your education.

    No, students are supposed to learn the material and have an exam that fairly evaluates this. Anyone who has spent time on those old terrible online physics coursework sites like Mastering Physics understands that grinding away practicing exams doesn't improve your understanding of the material; it just improves your ability to pass the arbitrary evaluation criteria. It's the same with practicing leetcode before interviews. Doing yet another dynamic programming practice problem doesn't really make you a better SWE.

  • Levitz 2 hours ago
    Humanization and responsibility issues aside (I worry that the author seems to validate AIs judgement with no second thought) education is one sector which isn't talked about enough in terms of possible progress with AI.

    Ask about any teacher, scalability is a serious issue. Students being in classes above and under their level is a serious issue. non-interactive learning, leading to rote memorization, as a result of having to choose scaling methods of learning is a serious issue. All these can be adjusted to a personal level through AI, it's trivial to do so, even.

    I'm definitely not sold on the idea of oral exams through AI though. I don't even see the point, exams themselves are specifically an analysis of knowledge at one point in time. Far from ideal, we just never got anything better, how else can you measure a student's worth?

    Well, now you could just run all of that student's activity in class through that AI. In the real world you don't know if someone is competent because you run an exam, you know if he is competent because he consistently shows competency. Exams are a proxy for that, you can't have a teacher looking at a student 24/7 to see they know their stuff, except now you can gather the data and parse it, what do I care if a student performs 10 exercises poorly in a specific day at a specific time if they have shown they can do perfectly well, as can be ascertained by their performance the past week?

    My Italian friends went through only oral exams in high school and it worked very well for them.

    The key implementation detail to me is that the whole class is sitting in on your exam (not super scalable, sure) so you are literally proving to your friends you aren’t full of shit when doing an exam.

    Just let students use whatever tool they want and make them compete for top grades. Distribution curving is already normal in education. If an AI answer is the grading floor, whatever they add will be visible signal. People who just copy and paste a lame prompt will rank at the bottom and fail without any cheating gymnastics. Plus this is more like how people work.

      I think the real problem is that AIs have super human performance on one off assessments like exams, but fall over when given longer term open ended tasks.

      This is why we need to continue to educate humans for now and assess their knowledge without use of AI tools.

      if we want to educate people 'how people work', companies should be hiring interns and teaching them how people work. university education should be about education (duh) and deep diving into a few specialized topics, not job preparedness. AI makes this disconnect that much more obvious.

    > We can publish exactly how the exam works—the structure, the skills being tested, the types of questions. No surprises. The LLM will pick the specific questions live, and the student will have to handle them.

    I wonder: with a structure like this, it seems feasible to make the LLM exam itself available ahead of time, in its full authentic form.

    They say the topic randomization is happening in code, and that this whole thing costs 42¢ per student. Would there be drawbacks to offering more-or-less unlimited practice runs until the student decides they’re ready for the round that counts?

    I guess the extra opportunities might allow an enterprising student to find a way to game the exam, but vulnerabilities are something you’d want to fix anyway…

    Instead of funneling more business/hype to the AI bro industry, to police the AI bro industry that fully expected this effect from their cheating-on-your-homework/plagiarism services (oh, I see this is a business school)...

    First, the business school administration and faculty firmly commits, that plagiarism, including with AI, means prompt dismissal.

    Then, the first time you have a suspicion of plagiarism, you investigate.

    After the first student of a class year is found guilty, and smacked to curb, all the other students will know, and I bet your problem is mostly solved for that class year.

    Then, one coked-up nepo baby sociopath will think they are too smart or meritorious to "fail" by getting caught. Bam! Smacked to the curb.

    Then one of those two will try sue, and the university PR professionals will laugh at them, for putting their name in the news as someone who got kicked out of business school for cheating. The business school will take this opportunity to bolster their reputation for excellence.

    At this point, it will become standard advice for the subsequent class years, that cheating at this school is something only an idiot loser does, not a winner MBA.

    Students cheat when grades are more valuable than knowledge.
    • semilin 18 minutes ago
      I think this points to the only real sustainable solution: make it so that students would prefer to do real work. We have seen for ages the distinction between seeming and being in regards to verbal understanding blurred. LLMs are only an acceleration of the blurring. Therefore it will at some point become essentially impossible to determine whether one really understands something.

      The two solutions to this are (1) as some commenters here are suggesting, give up entirely and focus only on quality of output, or (2) teach students to care about being more than appearance. Make students want to write essays. It is for their personal edification and intellectual flourishing. The benefits of this far surpass output.

      Obviously this is an enormously difficult task, but let us not suppose it an unworthy one.

      And then they complain when they gain no knowledge, can't pass the simplest of coding interviews despite their near 4.0 GPA, and blame it all on AI or whatever.

      In reality, they cheat when a culture of cheating makes it no longer humiliating to admit you do it, and when the punishments are so lax that it becomes a risk assessment rather than an ethical judgment. Same reason companies decide to break the law when the expected cost of any law enforcement is low enough to be worth it. When I was in college, overt cheating would be expulsion with 2 (and sometimes even 1 if it was bad enough) offenses. Absolutely not worth even giving the impression of any misconduct. Now there are colleges that let student tribunals decide how to punish their classmates who cheat (with the absolutely predictable outcome)

      I knew some hardcore, dedicated cheaters in college. All of them hit a wall where their cheating tricks stopped working. Most of them couldn't get back on track.

      I suppose there are other fields where the degree might be used mostly as a filtering mechanism, where cheating through graduation might get you a job doing work different than your classes anyway. However, even in those cases it's hard to break the habit of cheating your way around every difficult problem that comes your way.

      This is not hitting the problem. Most students in universities are completely fine with awful grades or expect comical levels of grade inflation. Ask a professor or TA and you'll hear about an insane level of entitlement from students after they hand in extremely shoddy work. Failing students is actually quite hard or extremely discouraged by admins.

      The real problem is students and universities have collectively bought into a "customer mindset". When they do poorly, it's always the school's fault. They're "paying customers" after-all, they're (in their mind) entitled to the degree as if it is a seamless transaction. Getting in was the hardest part for most students, so now they believe they have already proven themselves and should as a matter of routine after 3-4 years be handed their degree because they exchanged some funds. Most students would gladly accept no grades if it was possible.

      Unfortunately, rather than having spines, most schools have also adopted a "the customer is always right" approach, and endlessly chase graduation numbers as a goal in and of itself and are terrified of "bad reviews."

      There has been lots of handwringing around AI and cheating and what solutions are possible. Mine is actually relatively simple. University and college should get really hard again (I'm aware it was a finishing school a century ago, but the grade inflation compared to just 50 years ago is insane). Across all disciplines. Students aren't "paying for a degree", they're paying to prove that they can learn, and the only way to really prove that is to make it hard as hell and to make them care about learning in order to get to the degree - to earn it. Otherwise, as we've seen, the value of the degree becomes suspect leading to the university to become suspect as a whole.

      Schools are terrified of this, but they have to start failing students and committing to it.

    Is there an evaluation of how good the questioning was? Did TFA review the transcripts for that? Did I miss it?

    > The grading was stricter than my own default. That's not a bug. Students will be evaluated outside the university, and the world is not known for grade inflation.

    Good!

    > 83% of students found the oral exam framework more stressful than a written exam.

    That's alright -- that's how life goes. This reminds me of a history teacher I had in middle school who told us how oral exams were done at the university he had studied in: in class, each student would come up to the front, pick three topics at random from a lottery-ball-picker type setup, and then they'd have a few minutes in which to explain how all three are related. I would think that would be stressful except to those who enjoy the topic (in this case: history) and mastered the material.

    > Accessibility defaults. Offer practice runs, allow extra time, and provide alternatives when voice interaction creates unnecessary barriers.

    Yes, obviously this won't work for deaf students. But why must it be an oral examination anyways? In the real world (see above example) you can't cheat at an oral examination because you're physically present, with no cheat sheets, just you, and you have to answer in real time. But these are "take-at-home" oral exams, so they had to add a requirement of audio/video recording to restore the value of the "physically present" part of old-school oral exams -- if you could do something like that for written exams, surely you would?

    Clearly a take-home written exam would be prone to cheating even with a real-time AI examiner, but the real-time requirement might be good enough in many cases, and probably always for in-class exams.

    Oh, that brings me to: TFA does not explicitly say it, but it strongly implies that these oral exams were take-at-home exams! This is a very important detail. Obviously the students couldn't do concurrent oral exams in class, not unless they were all wearing high quality headsets (and even then). The exams could have been in school facilities with one student present at a time, but that would have taken a lot of time and would not have required that the student provide webcam+audio recordings -- the school would have performed those recordings themselves.

    My bottom-line take: you can have a per-student AI examiner, and this is more important than the exam being oral, as long as you can prevent cheating where the exam is not oral.

    PS: A sample of FakeFoster would have been nice. I found videos online of Foster Provost speaking, but it's hard to tell from those how intimidating FakeFoster might have been.

        Too bad. The premise should be that the instructor, by nature of having the position, already has understanding of the subject. As a student, you do not, and your goal is to gain it. Prompting an LLM to write a response for you does not build understanding. Therefore you should write unhindered by sophistry machines.
        • jimbokun 0 minutes ago
          But the instructor is not applying their understanding in any way. By delegating the evaluation to AI, there is zero value add vs just asking ChatGPT to evaluate your knowledge and not paying $1000s or $10000s in tuition.

          And universities wonder why enrollment is dropping.

      A written exam is problematic if you want the students to demonstrate mastery of the the content of their own project. It's also problematic if the course is essentially about using tools well. Bringing those tools into the exam without letting in LLMs is very hard.
      • Wowfunhappy 2 hours ago
        I don't entirely disagree but all exams are problematic. We don't have the technology to look into a person's mind and see what they know. An exam is an imperfect data point.

        Ask the student to come to the exam and write something new, which is similar to what they've been working on at home but not the same. You can even let them bring what they've done at home for reference, which will help if they actually understand what they've produced to date.

        The student has a lot riding on the outcome of their exam. The teacher is making a black box of nondeterministic matrix multiplication at least partially responsible for that outcome. Sure, the AI isn't the one grading, but it is deciding which questions and follow up questions to ask.

        Let me ask, how do you generally feel when you contact customer service about something and you get an AI chatbot? Now imagine the chatbot is responsible for whether you pass the course.

            The subject is "AI exams", not "exams". GGP expressed that they believe that AI exams would be an extremely unpleasant experience to have your future determined by, something I find myself in agreement with. GP implied that students deserve this even though it's unpleasant because of their actions, in other words they agree that this is unpleasant but are okay with it because this is punishment for AI cheating. (And which is being applied to all students regardless of whether they cheated, hence the "collective" aspect of the punishment.)
