<p>Are the tests really similar to PR's tests for Calc AB? I've taken one so far, and I did ridiculously well on it. As much as I would like to believe that's the actual difficuly of the test, it seems a little suspicious.</p>
<p>Can anyone here comment (from experience) aobut how similar the PR Calc tests are with the actual AP test? Also, if you know about Arco's and Barrons's tests' parity with the actual test, that'd be great too. Thanks!</p>
