<p>alright, so I went through all the material in the Kaplan physics book and I'm now going through the Princeton Review one. </p>
<p>I noticed, though, that there's so much more additional material in the PR book. Are there any extraneous sections in the PR one or is Kaplan just too easy?</p>
<p>help please, I really can't be bothered going through material that isn't even going to be on the test.</p>
