Adding context, the nearly-perfect-marks midterm was a take-home exam. Not that chatbots aren't a big problem in schools right now, but this same thing would've happened 15 years ago.
Not the same at all.
Take home tests are usually formatted in a way where it doesn't matter if the student has access to textbooks, or even the internet, since they still need to synthesize a response (thinking specifically of essay questions here, but it's not exclusive to them) that shows they understood the material.
LLMs can now do that now. Or at least emulate that.
Depends on the material. We had quasi take home exams in math because there was no reasonable expectation for you to be able to determine a series of proofs in an hour. We’d get a list of like 8-12 problems and like 5 would be on the exam for you to regurgitate your proof.
we had take final exam in a animal physio, but it gave a time limit so you cant just sit around searching google to look at all the answers. Also its done it a away its hard to search for the answers, and this was 10+years ago
