Are there any differences in terms of the content? I bought the CollegeBoard World History SAT II practice test booklet and when I was doing it, there were a lot of concepts that I didn’t know. Is there any additional material you need to know for the SAT II?
I’d imagine there are differences just like other subjects (i.e. AP Bio vs. Bio Sat II and AP Chem vs Chem Sat II).
The SAT Subject Test contains much more specific content than AP World’s general themes. Get the Barron’s review book to fill in the gaps
I agree with @TheKingofKings01, it’s MUCH more specific, like naming random people specific. However, if you take it around the same time as the AP test (so May or June), I don’t think it’s necessary to buy another prep book since you’ve already been studying for the AP test. I got an 800 on the Subject test and a 5 on the AP test using only Princeton Review (for the AP test) and butt tons of crash course and getafive.com
