What are some potentially unique methods you use to aid you during the actual test?
Mine is on the MCQs. On my scratch paper I make 4 columns and label them A B C D. Then I stick another column in front of those and number it for whatever MCQ I am attempting. Then as I'm answering a MCQ I will put an X next to whatever letter answer I am sure I can rule out.
It's not too significant, but it really helps me to completely block out the answer choices I am positive are not correct.
I don't think this counts as a test taking strategy, but I do jumping jacks and wall push ups in the bathroom during the breaks that I set up for myself. Its the only way I can stay awake enough to pass.
