Keep Your Routine (Score 1)

I tend to get very stressed before tests and especially finals (though I'm only a high school sophomore/junior next year so take this for what it's worth). I find that if I try to do anything special before the exam it makes me feel stressed because I'm treating the exam as a Big Deal. If I don't vary my routine and just show up for the exam like it were any other class, I'm calm and not about to rip my hair out. This has served me well, though obviously YMMV and these other posters definitely know what they're talking about better than I do.
