Best ACT essay/ SAT II Prep?

<p>My last ACT test (in Feb.) was a 32, with a 35 on Reading and a 34 in English.
BUT... my writing score was a 7. Out of 12. o.O which is apparently in the 42nd percentile.
As in, very BAD.</p>

<p>I think it's most because I have somewhat non-traditional english classes with very little emphasis on essays, and I don't think I've hand-written one since elementary school.
Obviously, I need to practice and study some books about writing, but have no idea which books actually help. Your opinion?</p>

<p>I'm planning to take the Math II & Physics SAT IIs in June, (I'm not starting too late on prep, am I?) and I'd love your take on the best books for those as well.</p>

<p>Thanks!!</p>
