I have 3 exams in the morning and I haven't slept at all?

I left everything to the last minute. Including revision. Revision for 3 separate exams.

I'm really angry at myself.

Even if I can sleep that will be for like 30 minutes or so.

How do I nap so short? It takes me 15 mins to sleep!

Anyways wish me luck and give me tips on how to cram all that revision fast?!!!

I'm damn nervous and I wanna kill myself right now! So upset.

Help I need to pass my exams
