<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>
