<p>Ok so, I bought the Kaplan book for Mathematics Level 2. But since then I haven't heard very good comments about it, and I looked through it and it seemed way too simple. So did I make a mistake buying it? Are there any other prep books that I could use?</p>
<p>I used Barron</p>
<p>Kaplan's not that bad, though take their practice tests with a grain of salt because they tend to be on the easy side.</p>
<p>Barrons will overprepare you, so I wouldn't say that's a good idea either.</p>
<p>A good book you can think about getting is Rusen Meylani's 15 Tests for 2C. That's a pretty realistic book (well, they're a bit harder, but not as ridiculous as Barron's tests).</p>
