Pulled an all-nighter to study for my calc final and my brain actually worked better the next day?

I mean I always heard all-nighters are supposed to wreck you. But I had my calc 2 final last Thursday and I just couldn't sleep no matter what. So I stayed up from midnight to 7am going over integration by parts and trig subs. Took the exam at 9 and I swear I remembered everything sharper than usual. Got an 87 on it which is way better than I expected. I don't get it. Maybe it was just the adrenaline or something? Has anyone else had a weird experience where pushing through exhaustion actually helped?

Oh MAN yes I had the SAME thing happen with my stats midterm last semester. I literally could NOT fall asleep no matter how much I tried so I just gave up and kept reviewing formulas and practice problems. Walked into that exam running on fumes and somehow my brain was like LASER focused. I scored a 92 and my prof even wrote "nice work" on it. I honestly think sometimes when you're too tired to overthink everything your brain just goes on autopilot and actually works BETTER because you stop second-guessing yourself. Plus the adrenaline from knowing you're running on no sleep probably kicks in a survival mode thing.

Wait a 92 on a stats midterm after no sleep? That's wild honestly. I got an 87 on my calc 2 final after my all-nighter and thought I was some kind of freak, but your grade is even better. The autopilot thing makes sense though, I remember just writing down integration rules without even thinking, like muscle memory took over. Maybe being too tired to panic actually helps with multiple choice sections where you just pick the right answer fast.
