<p>The only SAT II's I really feel qualified to take are Math I & II, Biology E & M, and Chemistry. How many would I need to take? What do colleges expect? Which of these would be the best to take?</p>
<p>For most colleges, you only need two. A few (ex. Harvard) require three, so technically you could get by with three, but if you can score amazingly well (750+) on more without too much effort, then by all means, do them. I'd recommend Math Level 2 as one you should take; the curve is very generous, and Math I is too much like the SAT I.</p>
<p>^^ agreed. From what I've found, only Harvard, Princeton, and Yale require three. It's funny, 'cause other top colleges don't follow the same: Stanford requires none (but recommends them), and MIT only requires two (and allows either Math 1 or 2, which colleges like Berkeley don't). I have a feeling that for some colleges, the subject tests are just more ways of eliminating mediocre applicants (who won't take the tests, etc.).</p>
<p>Georgetown requires 3</p>
<p>If you are applying to any of the schools that want 3 SAT Subject Tests (add Johns Hopkins to the list, although they only "recommend" 3, they don't require them), you should know that they would prefer 3 different subject areas, not 1 math and 2 sciences.</p>
<p>Can you take more than one SAT II on one test day?</p>
<p>yes, you can take up to three in one sitting; but if you want to cancel one of your scores from that day, you have to cancel all of them.</p>
