<p>I have been struggling in my Physics class for a while now, and I have finally decided to try and get some help. </p>
<p>First, what study books are best for the AP exam and subject test? I currently have Princeton Review for the subject test. </p>
<p>Also, can anybody give me a good source for conceptual questions relating to topics covered in this course? I seem to have the most trouble with those types of questions. </p>
<p>I took it last year and got a 4. I feel now (I’m in E&M with a GREAT teacher, explains everything). </p>
<p>The important thing is to learn to build your own equations and use systems of equations. One problem a few years ago was a torsion pendulum, in which a mass “m” was attached to a string, which was wrapped around a pole, which spun and twirled 2 masses at the top. You had to relate tension to torque to moment of inertia etc. Just be confident.</p>
