How to improve ACT score / get more practice tests

<p>Hello, I'm a junior at a semi-competitive high school and I need major help on the ACT. At the end of my sophomore year, I used the real ACT book and Princeton review to study and ended up scoring a 30 composite (34 math, 32 english, 23 reading, 29 science, 10 writing). I really want to get at least a 33 composite and I'm planning on taking the ACT again in spring. I had already used all the practice tests in both review books at least twice and I feel like it'd be counter productive to use those books again to study the next time I take the ACT. My question is, are there any practice tests that I could use that would give me a good idea of what the real test would be like that aren't in either of those books? Also, what can I do to make my math more consistent and bring my reading score up?</p>
