This year my I took 3 AP classes AP Macroeconomics, AP U.S. Government, and AP Human geography.
I picked up a couple of prep books and started to read them and most of the information was not taught in my classes.
I am starting to study now, but I am not sure If I will be able to get a 5 on all 3 , since most of the information is new to me, and it is almost like self studying. Does anyone have advice?
If you are diligent, you can make it happen. Macroecon and human geography are typically considered easier AP exams so this may help ease your concern, but you should still study until you are thoroughly comfortable with the material. Crash Course US Gov and Economics videos may help you to review or introduce yourself to the material you should have covered in class. Good luck!
