<p>Do people bother taking them? For example, I'll be taking AP bio senior year, thus I'll probably be able to score pretty well on the SAT II in the case that I take it... would it be a good idea for placement in college, or will my AP scores serve that purpose?</p>
<p>Unless the school specifically says that it uses SAT II for placement (for example, some schools use Math or Language SAT II's for placement), your AP score should be sufficient. </p>
<p>Of course, when in doubt, call admissions and ask about their policy. (It's easy now that there's only one school involved!)</p>
<p>SAT II's are usually used for admissions / course placement (don't rely too much on this). Most competitive colleges have their own placement exam for certain subjects. Your AP exam score can help you place out of a credited course. There's a subtle difference between the two.</p>
