Hey all, I'm planning on taking SAT IIs on Saturday in Biology and US History. I took AP classes for both subjects and have AP review books ie: AMSCO + Cliffs, REA. Do you reccommend I get a specific SAT II review book or collegeboard's real sat II book? Which is better to get, "The Official Study Guide for All SAT Subject Tests" or "Real SAT Subject Tests" by collegeboard? Any help would be appreciated.
