This year (Junior Year), I am taking AP Comparative Governments, and I think it might be a good idea to do AP US Govt exam as well, since I heard that US Government isn't as challenging as others. However, my school doesn't offer AP US Govt course, so I decided to self-study. In Thailand, it is very hard to find international textbooks, especially about this subject. So I got myself two review books (Barron's and Princeton), since the only way to get myself a textbook would be ordering it from the States. This will cost A LOT!
My question is can I just use review books to prepare myself for the AP US Govt exam coming in May. Do I need to get other prep material as well? I do have time to self-study, I guess. As I'm taking AP Comp Govt, I think I will be absorbing some additional background for the US Government since I believe there is one chapter in my Comp Govt textbook that covers US Politics.
PS. This is my first post on CC, so it might take sometime for me to reply. Sorry for my grammar mistakes too.
