Alright what is the worst thing that can happen during a paper?

To me the worst thing is BLANK OUT! Oh my gosh. .

Yesterday while going over for my first paper, i'm dare confident that i will score with flying colours, but yet, when i was sitting in the hall. . . BLANK OUT!

Imagine! blank out and look totally blur down at the hall with time ticking away. Raarrrr!
Oh well... Released some frustration to cool myself down for the next paper, hopefully this wouldn't happen again! =D
