<p>You want to concentrate on the AP exams that will give you the biggest bang for your buck. That means that you need to check the websites of the colleges/universities that you have been accepted to (no acceptances yet? then check the places you have applied to), and find out which AP exams will get you credit and/or placement for classes that can replace some of your general education credits. That will leave you more time to concentrate on your major, and on electives that you really do want to take.</p>
<p>For example, if you know now that you are an English Lit major, and the Physics and Calculus exams will get you out of your math and science requirements for your degree, take them. It is probably as waste of time to take exams that will place you out of the introductory course in your probable major. It usually is better for you to take that class at your university so that you get the basic training that the rest of the major is built on. However, it may be worth a call to the department to find out what they think. If students with a 4 or 5 on the AP exam normally jump successfully into upper-level courses, taking that exam can save you time, trouble, and money.</p>
