i will study early in the morning on that day like 4.30am
liddat. (i'm an early bird ok). then i will study throughout the
bus journey, trying to picture all the lecture slides in my head,
not really reading the words already. then, half an hour before the
start of the test, i put everything away. and just go toilet, sit
down and look around, watch people desperately cramming in last min
stuff. then i go into exam room, sit down, write matric number, put
matric card on table, drink a mouthful of water, put on my jacket
etc (bascially settle down)
then, i pray.
"Lord, please help me in this exam paper. help me to answer the
questions to the best of my abilities. and also help my friends in
theirs. give me the grace and wisdom. amen."
then i wait for start of paper closing my eyes.

thats my secret formula.
