I took my test almost two yrs ago and it was easy because
1. i had a really awesome teacher and actually prepared us for the test
2. i like history/politics
the test had multi choice, DBQ, and free response essay portion. The essay choices span throughout our curriculum -- there was one question from the early government (Jefferson, Adams etc), FDR (with comparing his New Deal with Wilson's Great Society), and finally Vietnam. So try to get the big main concepts of the beginning, middle, and "end". I'm surprised i still remember it! But if your thinking about taking this class it would definitely be helpful if you also want to take AP Gov't. Also course-notes help a lot with outlines and notes.
