<p>I am looking to buy some prep books. Please advise on your favorites.</p>
<p>Thanks</p>
<p>The official ACT Red Book -Definitely buy it
Others are
Barrons ACT , Princeton Review</p>
<p>Starting out, I would definitely agree that the Red Book is the way to go. It has several practice tests that seem to be within close caliber to what is actually on the test. Good luck studying.</p>
