<p>I'm in the College of Chemistry, and I'm going to take Physics 7B next semester. I got a 5 on both Physics C tests so I got to skip 7A. My question is, even though I have to take 7B as a pre-req for a chem major, will I get fewer units or something since I already took the E&M AP test? I know that some classes can "duplicate" units from AP and you get fewer units as a result.</p>
