How accurate are Barron's and Princeton Review's practice tests?

<p>I have the Barron's sat 2 math book and the princeton review physics book. I would like to know how accurate are the practice tests for those who used the books.</p>

<p>inaccurate as hell. they're sooo off man.</p>

<p>Can you be a little more specific?</p>

<p>like how?????</p>

<p>difficulty and content. Are the tests in these books similar to the real tests?</p>

<p>I used Barron's for math II- the book tests were ridiculously harder than the actual one, but I felt that prepared me well enough that the real one was pretty easy, and I scored very well. Dunno about the other book though.</p>

<p>Well does Barron's math teach you everything that you have to know for the real thing. I wouldn't mind learning extra because I do IB.</p>

<p>The scope was excellent- it teaches you more than you need to know, and I felt it adressed every topic that came up.</p>

<p>What about Kaplan's and SparkNote's? Which book's practice tests are the MOST accurate?</p>

<p>From my experience, the REAL SAT II published by the collegeboard is the most accurate of all, within a fluctuation of plus-minus 30.</p>

<p>what does the real sat II contain exactly?</p>
