<p>I wouldn't underestimate the power of a good night's sleep, either. DS1 went in cold to the PSAT in 9th and 10th -- barely remembered it was happening, did no prep, and didn't get more than 6-7 hours of sleep.</p>
<p>This year he got 10 hours the night before, got himself into "test mode" (bacon, cereal and a can of Jolt for breakfast), and raised his score 22 points. He readily admits he is useless without a good night's sleep -- an important self-realization he will need to keep in mind as he starts thinking about dorm life, roommates, etc.</p>
