The advantage(?) of take-home exams à la Caltech is that they can be open everything and 3–5 hours long :-P (For what it's worth, being able to listen to music during an exam, ctrl+F a digital textbook, etc. was super awesome; it would deeply sadden me if that becomes infeasible in the future once enough students stop caring about the Honor Code....)
They were finals, not ordinary tests or midterms. Junior and senior year, I think one was Chemical Engineering, but I can't remember the exact name or number.
Things may have changed, but I don't recall any group exams during my time at Caltech, and conversely I do recall a strong sense of pride in the Honor Code. Also, if your professor allows collaboration, then it's definitionally not cheating: There is a vast moral difference between "the professor made the assignments difficult with the specific expectation that people will collaborate" and "the professor doesn't want collaboration but people did it anyway".
Frankly, this comment feels almost entirely foreign to my experience—I suppose things could've changed over the years (although my impression is that things have gotten much worse recently, not better), or it could be major-specific, or I just got lucky with the specific people I happened to hang out with?
I'm not the other commenter (and I believe you that it's not AI), but I'd guess it's mostly the first line: a short affirmation followed by "The problem is ...." feels like the sort of formula the LLMs love to use. (Not trying to imply that there's anything inherently wrong with it, of course.)
While we're at it, I'm under the impression that the recent LLMs have also co-opted "genuinely", which I'll never forgive them for—first they stole my em-dashes, and now they're stealing my adverbs too?!
It's just that, in my (uninformed) opinion, Anthropic is incentivized a priori to claim things like this about their models. Like, it's probably really good marketing to say "our product is so smart, and we're so concerned about ethics, that made sure a psychiatrist talked to it". I guess it's ultimately a judgment call, but to me the conflict of interest seems big enough that I'm really wary of this sort of argument. (I'm reminded of when OpenAI claimed GPT-5(?) was "PhD-level"—I can personally attest that, at least in my field, this is totally inaccurate.)
Indeed, that is (allegedly) the case with organ donation: https://www.nytimes.com/2025/07/20/us/organ-transplants-dono...
