<p>I'm a junior now. Applying next year to engineering/science courses. I took the SAT Subject Tests for Physics, Math II and Chemistry and got 800. I'm not sure if I should do some more tests -- although most schools require only 3, I'm afraid there isn't balance in what I'm taking. If I were to take some more, I'd probably take Biology (E or M), Literature and USH. What do you think?</p>
