I've done it so many times ...most of the time it turns out alright but sometimes I literally black out mid way through the exam / test and forget EVERYTHING. It's a real problem but I get so much anxiety that it becomes difficult to sleep before a test
hbu?

Yes and it's rarely a good thing

LMAO .. I do sometimes ... I once took a test without sleep or studying for it.

Yeah I did at least once in college. Don't remember what I got on the test though

Literally all the time lmao. And it's just because I procrastinate.

Hmm i dont think so. I did a presentation without sleep tho

I've had close to no sleep for really important exams. It's so hard to power through

Yes. And aced it.

I've slept for mostly 2 hours before some tests for sure

quite a few.

Yes like last week. 99% sure I failed because my brain would not work. It was a really tough Calculus 2 Exam and I decided the night before would be the perfect time to take an energy drink for the first time ever
I felt like I had ADD and schizophrenia. It didnt even help me study and I crashed really hard. Never again

I can't remember the time I did sleep for an exam, but that is just because I always start way too late and study better at night.

Did it today (I got a few hours of sleep though).

No, but I'm about to do it on Sunday I fell into really bad habits this semester and I'm just trying to slide by with passing grades. I need next semester to begin already for a fresh start.

Never! I have at least 5 hours of sleep during exams week It's easier to remember things if you take a nap after studying.

Here's a tip: Study 1-week ahead so that you won't end up cramming and failing the exams!

Once, never doing it again.

Yeah I'm gonna get less then 3 hours of sleep today. I have a test on a frigging Saturday

Isn't the brain actually more active for a little while after an all nighter before completely shutting down ?

All the time

Rarely, but yeah.
