i'd suggest going through a kaplan or
pr sat ii physics book just to learn what you need to learn and then you can skip/skim what you already know...
barron's WAY overprepares you (i flipped through it and could tell right away), so you would waste a lot of time studying things you don't need to know...but if you just wanna study the basic concepts (of each topic, of course) then that should be fine...
