<p>I took the ACT in June and got a 21 and I plan on running through these books in August.</p>
<p>In Order:
1. Princeton Review's Cracking the ACT
2. Princeton Review 1296 ACT Questions
3. The Real ACT Prep Guide</p>
<p>I want to raise my score to a 27. Would this be good enough? Should I get different books?</p>
