<p>I've used the Princeton Review for several SAT Subject tests, and I'm about to use it for AP US Government and Politics. I've heard a few rumors that PR isn't all it's cracked up to be, and that there are better books out there. I originally went with PR because I preferred it's format and style of writing to those of other books. </p>
<p>Are the PR books too easy? Are their practice exams to easy? I always got high/perfect scores on the practice tests, but I didn't get perfect scores on the actual SAT subject tests. My real scores were pretty high, but not perfect. I decided that I got perfect ones at home because I was less stressed.</p>
<p>If you don't think PR is good, what series do you think is good? What series do you/did you use?</p>
