<p>These questions may have been asked several times, but I tried digging around the forum and couldn't find a straightforward answer, so here are the questions:</p>

<p>1) Are there only 2 OFFICIAL Math IIC tests released by CB - the ones in the Official Guide to Math IIC?</p>

<p>2) Which practice tests are the most accurate to the real test? Sparknotes? PR?</p>

<p>3) If you get 700 in Meylani or Barron, is it equivalent to an 800 on the real test?</p>

<p>and what about the sparknote test online? I've done the PR one and got 800 or 790 at least and while doing the one of sparknotes I can't manage to get over 730...</p>

<p>I took about 5 barrons practice tests and got ~650 on all of them, and totally stressed out. I ended up getting an 800, so it's been my experience that the barron's tests are way too hard.</p>

<p>I also took a test out of collegeboard's own official book and got a 770. So, if you're getting 700 in barron's then get ready to ace the real test.</p>
