SAT II: For admission or placement?

<p>I've been reading that some want these scores for admission and some only use them for placement. Which one are they more commonly used for? My concern is that my physics score "average" (right in the middle 50%), but the physics class i took was poorly tought. So I hope this will not hurt my chances at places too much.</p>

<p>Admission. AP grades are for placement.</p>
