<p>I don’t know if you will do well, but studying for APUSH helped me with the SAT II because I took the AP first in May and then took the SAT II in June so the material from APUSH was fresh in my mind. I will say though that while APUSH questions tend to be more analytical and critical thinking, SAT II US History is more factual so you could maybe go over more US history facts before the SAT II.</p>
