Hello Mindy and I want to welcome you to IC also!
In addition to studying the IC flashcards, I would read, "The Complete Idiot's Guide to American Government" by Mary M. Shaffrey & Melanie Fonder. Very good concise book.
I don't know what your "testing" goals are but if you are going to wind up taking U.S History I & II down the line, it would probably be to your benefit to take these two exams before the American Government CLEP. From what I've read from others on this forum, this is a good order to take these exams. Others opinions may differ, but this is the strategy I will be utilizing.
I would check out your local public library first to see what resources they have available before purchasing materials. The library is a vast source of information...and it's free!
I would also check out some online resources as well. Try
Google Video , they sometimes have videos on certain subjects.
Just for future reference, always check out the Specific Exam Feedback section before you start studying for an exam. There is an abundance of information there so don't sleep on this. It has helped me and many others tremendously. I would also try to grab a copy of the Official CLEP Study Guide, 19th edition by the College Board. If they don't have it at your local library then I believe it will be worth buying. Especially if you are taking alot of CLEPS.
Hope you find this information helpful.
Peace be unto you.
From a loyal degree seeker,
Marshall
