<p>I checked out this book from the library a long time ago and just finished taking the practice tests in US History and Math 2. How accurate are these tests? I got a 710 on the USH (should have been a 740 except for stupid reading mistakes) and an 800 (barely) on the Math 2. I don't want to get false confidence (plus my US score left a bit to be desired). Just as background info I got a 5 in APUSH and am currently in Calc AB (highest math available at my school). In addition, how difficult is the Chem subject test compared to AP Chem multiple choice. I haven't reviewed much for chem and the test is in 9 days, but I got a 5 in AP Chem as well so I do have a knowledge base for cramming.</p>
<p>They are the most accurate tests out there.</p>
