I finished my red Real ACT Prep book. Are there any other good ACT prep books?

<p>I hope to find a prep book most similar to the actual ACT. I still need to practice some more. I've been printing ACT sample tests, but I'm almost done with those, too. Please help!</p>

<p>Princeton Review’s “Cracking the ACT” and “1296 ACT Practice Questions” are phenomenal. </p>
