<p>I am looking for the best of the best of the most helpful books. I've looked in book threads and while helpful, it was all over the most place with people recommending different things and no general consensus. So, please, can people tell me what are the books I should get if I am taking World History, US History (and should I study for this if I take the APUSH exam before the SAT 2?), Physics, and Math I. The only book I know that everyone loves is Barron's Math II.</p>
