Ways to study for ACT and SAT?

<p>I have a couple of books for SATs and ACTs, but personally I don't feel like it helps me much and I need more practice. Are there any good ways to specifically practice?</p>

<p>I have an iPhone and I bought the Allen ACT app for like $5. I practiced while waiting in line, when I was done with lunch, and whenever I had a spare moment. I feel like that was really helpful. (34 ACT)</p>

<p>Just don’t.</p>
