<p>I just wanted to know what people thought were the best books for AP US history and AP Stat. Also, is it necessary to buy a book for the SAT II US History if I buy an AP Book? If yes, which SAT II book should I buy?
Also, how hard is it to get a national merit scholarship from the PSAT in NJ?</p>
<p>does anyone know the answer to my questions?</p>
