3 tests?

<p>Which of the top colleges (can be ivy or non ivy) require or recommend 3 SAT II tests? I've only taken 2 (800 Math II, 780 Biology M) and would consider doing another if necessary. I've also heard that ACT's can substitute SAT II. Is that true, and should I do it?
Also, are those scores good? What else should I take in December (not literature since I'm bad at CR and it has a harsh curve)?</p>
