Demoralised/Fuck up

i am really going to blow soon, just got back my POA results, very near passing mark, paper 2 pulled me down, i failed paper 2 of POA and 1st time so low in Paper 2!!!!!!. I am including POA in my L1R4, this prelim reeally demoralised me and i felt that i fuck up in this examination.Why is it that, no matter how much i remember the facts, it always avoids me in examinations, what's wrong with my brain and memory, just now when i received my POA paper, i really really WANTED to tear the paper apart and burn it. I am planning that the remaining 1 and a half months, i will push all the way and not let anything stope me from getting my good grades, OH yeah!! you can count on that!!!!!!!!!!!!!!!!. By the way, the songs below playing is how i feel right now!
