<p>Im registered for 3 SAT II's: Math II, Chem, and Physics. I'm 100% sure I will get 800's on Math and Physics, but for Chem I'm not so sure. What will happen if I, say, only take the math and the physics that day, and totally ignore the chem? Will my Chem score come back as a 0, or a 200? Will any1 know I didn't take it??</p>
