How long have you functioned without sleep.

[DinRaat.]

I have a few tests coming up, and I have close to 0 preparation, in other words, in a scale of 1 to 10, I have 110% screwed. And I need to pass, by pass I mean not scrap a 50 but get 75+.

Is it possible to stay awake for close to 2 days straight with minimal amount of sleep lets say for 3-4 hours. I am desperate

I am already stocking up on Monster/Red Bull.

This is my plan

Go to sleep at 11:30pm- Wake up at 6:30pm Study Till Permutations and Combinations till 12pm, From 12-10:30pm study Algorithms and data structures.

Repeat for the next 2-3 days.
