aaaaaaaargh!!!!! i feel like killing myself right now...seriously...the last question of maths paper 2!!!! aaaaaaaaaaah!!! i blanked...i just couldn't remember how to find sample proportion...but i knew that i knew how to find it but it just wouldn't come to me at that point!!!!! so i left most of the question out!!! and then i realize after the paper that it's the simplest thing in the world!!!!! if i hadn't known how to do it at all i wouldn't feel so bad...but the thought that it was so simple and i knew exactly how to do it is killing me right now!!!
