<p>I just got the book which simply includes two full length tests. I think that the tests are kind of hard ? what do you guys think ? ( for instance, these tests were harder than the sparknotes's )</p>
<p>Those tests [PR’s] closely mimic whats to come on real test. ;)</p>
<p>I found the PR tests a little harder than the CB test, but only a little. Sparknotes is definitely on the easy side.</p>
<p>The test in the official CB guide should give you a pretty accurate estimation.</p>
