Exam: Freak Out

Exactly 2 more hours from now, I will be facing my exam paper. I am damn scared now... Freak out. I don't know why i have to fall sick 3 days before exam. Then slept whole 2 days and I'm left with 1 day for final revision. I can only browse tru' some important part which I feel like will come out for the exam. That's it. That is all I can do since I'm running out of time. Wish me LUCK!!!
