<p>All I'm really interested in are the practice tests....so whose do you think are the most <em>helpful</em>? </p>
<p>I know that Barron's is harder than the real and that McGraw Hill's is easier....(btw, any more info regarding difficulty of various books' practice tests would be nice :).)</p>
<p>But as for which tests were the most <em>helpful in preparing</em>, which did you find was the case? (When I say a test is helpful, I mean through refreshing the subjects in your mind when you see specific questions that you might have forgotten about, + answer explanations for all.)</p>
<p>Also, if it helps any, I just took a couple PR and got around 740, then skimmed my AP chem notes, took a McGraw Hill's and got an 800 on MH. I plan to do the rest of the McGraw Hill's, but in case those really are too easy...does anyone else have any recommendations?</p>
<p>Thanks a lot!</p>
