Best book for a low science score?

<p>Hi there,</p>

<p>I took the ACT for the first time (didn't do any prep) last June and got a composite of 32. The breakdown was 35 English, 31 Math, 34 Reading and 27 Science. I'm planing to retake it in the fall for maybe a 34-36.</p>

<p>I bought the ACT Barron's book and have not used it yet, but have seen the Red official book being recommended a lot. Which one is better for bringing up a science score to the high 30s? What about for math? </p>

<p>I’d just keep taking practice tests personally. Didn’t use any book to raise my science score and it went from a 26 (Feb) to a 32 (May) to a 34 (June).</p>
