<p>I'm taking the C test and based on the advice of other people who took it last year at my school, I'm going to be studying from my notes and taking lots of practice tests that my teacher is giving us. I'll probably grab a few review books from the library and skim through them to make sure I've covered all the concepts.</p>
<p>I'm taking the C exam this year, and am using the Princeton Review, my notes from class, and practice free responses and multiple choice questions from past exams (which i got from my teacher). </p>
<p>I think it would be the most beneficial to do questions from the past exams...the princeton review also does a very good job of explaining various laws/thereoms. </p>
<p>Also if you go to collegeboard.com, i think they have a percentage breakdown of specific topics that will be covered on the tests...you can just go through that, and plan your studying accordingly...</p>
<p>I would suggest taking at the VERY least one full practice exam in the test conditions; analyze afterwards what questions you got wrong; then study up on these areas (for instance, I recently took a physics C practice, and I'd completely forgotten about ocillations and a lot of e&m, mostly induction).</p>
