sitting at the front of the room helps me, so i can't see anyone else. in my prelim exams i sat at the back, ot of habit, coz i hate people being behind me. but seeing everyone else writing down answers when i couldn't think of them myself made me nervous. i'm in the middle of my final exams and i've been sitting at the front and i've been doing okay
also, i go through the paper once only writing down the answers i definately know. then i go through it again thinking a bit more on each one. then again and write down a load of crap for the answers i don't know lol but i have gotten marks for the load of crap before lol
hope i helped a bit
good luck
