Best ACT Prep Book For a 34+?

<p>I just got the (unofficial) results of the ACT back and my break down was a 32 E, 31 M, 35 R, 31 S, with a 32 composite score. I basically only need to raise my score by one point in any section to get a 33 composite, but I'd like a 34. Are there any recommendations for books that are better for doing harder problems and making the jump from a 32/33 to a 34/35? I own the red official book already, but there are only five tests and no real review sections on what's covered in each part.</p>

<p>^I’m in the same situation, I need to get my 32 composite to at least a 34 by the December test date.</p>
