<p>the website offers several practice tests for sat subject tests (as well as ap) how realistic are they?</p>
<p>Trust me, they're really not realistic. Or at least for AP US history, they're not. And they don't even have free-response questions, I don't think.</p>
<p>The Math 2c one is pretty accurate, but I've heard that sparknotes isn't too accurate beyond that one...</p>
<p>no for bio then?</p>
<p>some are really easy and some are really hard. ap bio is really easy and the sat bio has some random stuff irrelevant to the actual exam.</p>
<p>How about for Physics?</p>
<p>and what about us history?</p>
<p>id say pretty easy. i havent taken the actual collegeboard exams in physics and us history, tho. ok, id put it this way. i took the sparknotes us & ap world history exams & got a 5 & im a freshman.</p>
