Please Help!!!!

<p>HI</p>

<p>Due to certain scheduling circumstances, I was forced to take an online AP (emphasize AP) class because I need 4 history credits to graduate from high school. I regret this decision, but nothing else could be done as there was no option for a regular US hist. online class. Anyway, now my problem is that I am extremely far behind (think 1600s) because the class is so lenient about due dates and such. I spent my time in that class studying AP chemistry (a class I willingly took and definetely want to get a 4 or 5 on). Now I want to basically start from the beginning. I have the AMSCO AP US History book (which I bought because of its good reputation). Considering the limited time I have, I want to know want can be done with the AMSCO book to get at least a 4. Please help!!! I am really nervous. I know I brought myself into this mess, but please help. Should I just drop this class and thoroughly read the AMSCO book? of corse answer the mcs and some essays also.</p>

<p>Thanks</p>
