SAT CHEM practice test

<p>Which prep book's practice tests are most similar to the actual test?
I have barron's, Kaplan, Mcgraw-Hill, and Princeton review.
I took the real test from the collegeboard book, and it seemed harder then Mcgraw-hill and Princeton Review..
which ones should i take?</p>

<p>i never took chem but for physics us history and math 2 i used both kaplan and princeton review for all 3 and i thought they were good
i initially bought a mcgrawhill book for math 2 but it was full of math errors so i threw it out</p>

<p>for math 2, were ur practice test marks similar to the real score?
Do kaplan and princeton have the most similar practice test for math 2?</p>
