38hours without sleep - Is it possible and okay? Need urgent advice!!!?

Question

I have a REALLY important exam tomorrow.
And I want to revise a lot more stuff about it, And I was wondering if I don't sleep for 38hours in a row could i still do well in my exam and allow my brain to function okay if i eat breakfast, lunch, dinner, tea - energy drinks and vitamins?
Could i do it this way? It's the only way i can get good marks as i have loads of revision to do?
When i come home from the exam i can sleep all day and night if i wanted too?

No. 24 hours can work, but not more than that. Your brain reaches a certain point where you cannot retain anymore information without rest. It has also been shown that severely sleep deprived people function at the same level as tipsy people.
You also don't want to be fried before you even take the exam! Plus, you'll be kicking yourself if you make stupid errors, which lack of sleep greatly increases the probability of.
Do what you can today, and go to bed super early. Then get up early, and refresh your memory. Reviewing right before the test is a huge key to success. If there's something super important that you're having trouble with, like a formula, write it on the top of your exam as soon as you receive it.
Please do sleep, but determine how much you're going to based on what kind of exam it is. If it's multiple choice, allow yourself a little more time to sleep. If it's short answer/essay, you would be better off sleeping a little bit less, because recognition is easier than recall.
I don't know what time your exam is, but I would recommend going to bed at 9:30 PM tonight, and waking up at 6:30 to review.
I feel your pain, I'm a professional procrastinator. Trust me, staying awake for more than 24 hours is only going to make things worse.
Good luck, you've got this!! :)

It's not healthy to do. It takes longer to die from water deficiency, than it does for sleep deficiency which shows that the brain requires sleep, otherwise it won't function properly and can "shut off" (death) if it doesn't have enough energy. Your brain will not perform to it's highest potential when it is sleep deprived so you would be jeopardising your exam as well as your health. Also, whilst you sleep, your brain processes what you've done that day, including what you've learnt and turns them into memories so sleeping will increase the likelihood of you remembering your revision.
You should revise weeks before an exam, not the night before.

Nope. Sleep is designed to re-energize the body. Without sleep, your reflexes slow, your vision can temporarily blue from fatigue, you can become more irritable, recall becomes poorer and you may actually see intermittent episodes of sleep that will prevent you from finishing the exam in the allocated amount of time.

my science teacher holed up at a Dennys restaurant and crammed for like 2 days straight she said and she thought she was okay and she was certain she got everything prepared for it but when she went to take her exam she forgot her fucking ID and couldn't take it. so no your brain won't function properly.

You could definitely stay up for that long, but plan beforehand and make alarms or checklists for all the things you need to get done. Even if you're able to retain all the information you need to in order to successfully complete your exam revision, your brain won't be able to catch the little things you might forget (ID, supplies you may need, etc.), so make a system for yourself ahead of time to try and avoid that pitfall.

I've stayed up for several days straight to prepare for an exam before; after the first 24 hours you're usually too tired to actually feel the need to sleep (if that makes sense). I'd advise against using energy drinks, since after a few hours you'll crash and taking another one to try and recover from that might make you sick.

Drink plenty of water, though, and try not to eat high carb meals because your body will feel tired from all the work it takes to break down the carbs into energy. Also avoid really sugary drinks and snacks; you'll either crash from all the sugar or get a terrible headache.

I'm constantly pulling all-nighters and I can honestly tell you that pulling an all-nighter before an exam is no fun. Sure, you've looked over all of the material but your mind feels very 'foggy'. Personally, I'd rather get at LEAST 2-4 hours of sleep. Just enough to get any rest at all.

Unlikely the human brain needs 10 hours of sleep to work properly.

I tried to learn ones, after 24 hours my stomach went sour and I had to lie down. Next I slept very long, and afterwards I woke up groggy.
After several sleep experiments I can tell you, the human is not a robot, and works best in 3 hour intervals with a long break afterwards.

I've gone 24 hours and walked into an exam.It was worth it.
At other times I've gone 90 hours, but that was just working around the clock, without too much thinking.Some people can do it better than others.Try a few doses of vitamin B, then vitamin C every 2 hours (no more than 1000 mg) if you're not used to it.

It's possible but it's not okay. I did it twice during 24 hours for the same reason as you, but I wasn't feeling well.
My head was hurting and my eyes were very tired. Plus, it seemed that my brain was working slowly.
I won't do it again and I don't advise anyone to do it.

Nope that won't work. Your brain won't function correctly for the exam. You need to sleep at least minimum 5-6 hours each night if your body can handle that before an exam if you want to be at maximum potential during the exam.

You'll do worse. If you study all that time without getting sleep, you'll just forget it or be so out of it that you'll answer questions wrong even if you didn't remember things. The brain needs sleep to process memory.
