<p>AP Physics E&M
AP Govt & Econ
AP Bio</p>
<p>So as a senior next year I'm taking those 3 AP's (among others) and I want to get a little head start on the course material before next year. I might even learn all the E&M subjects/concepts so it won't be too grueling throughout the year. </p>
<p>For Bio I already own the 5th edition Campbell book so I'm mainly looking for a great AP review book.</p>
