Self Study AP US Govt, USH, and WH

Any tips? I’ve taken two years of World History and one year of United States History. I read a few questions on an AP book for those and they looked pretty doable. I haven’t taken an AP social science class, though. What content should I brush up on myself before the tests? What about AP Comparative Govt?

I would also know how the content compares from AP USH and WH to SATII USH and WH.

AP is harder than SATII in general

I took the APUSH (4) exam and the SATII last year. I’m not sure about the other two, but the AP test is mostly synthesis and being able to remember info over time/compare to other info whereas the SATII was just regurgitating specific facts.

Thanks! I noticed that part on SATII. Since I am better with synthesis, I might perform better on AP (or maybe the difficulty will balance it out). I’ll review some of the exams lager though.
