<p>What is the best ACT prep book that you have bought? Why would you recommend it?</p>
<p>I reccomend a conction of sources. First, the Red Book by the makers of the ACT. It has 3 old ACT tests that are very accurate at prediciting how you'll do on the real thing. Second, the Pricenton Review: Cracking the ACT. It refreshes all that material you might of forgotten over the years and brings to light all the question types and how to answer them. However, the Reading section in PR is crappy so I reccomend using sparknotes online, which is free, to cover that section.</p>
