Best books for Sat II chemistry and physics?

<p>Hi, I'm taking AP chem and physics next year and I also want to take the subject tests but I had the worst chem honors class ever and my physics class wasnt too great either.I plan on studying over the summer and taking the tests on the first date available. What are the best books for chemistry(I barely know anything) and physics(I know a good amount but not enough to do really well) to help me get a score in the 700's or even an 800. </p>

<p>Also,I generally prefer review books that are a lot harder than the actual test so I can be ready for any question. I appreciate any advice you guys can give me.</p>

<p>I heard that The Princeton Review and Barron’s are really good for Chemistry and Physics</p>

<p>Those are the one’s I’ve been looking into but I dont know which is better or If i should just get both PR and Barron’s</p>

<p>If you are looking to get the highest score possible (ex. 800), then it’s recommended that you get both books and possibly even more for the practice tests. On the other hand, for physics sparknotes is also a great book.</p>
