<p>I am taking Math 2, Chem, and US History subjects on June 7. I currently take PreCalc and AP Chemistry, however, I am in a regular US History class, so the content is not adequate for the subject test. I was wondering what book I should use for US history and is the Sparknotes (link below) enough for the subject and if not, does it have all the topics being tested on though at least?</p>
<p>Thanks!</p>
