<p>All I hear about is The Real ACT book or PR 1296? Or whatever...but what about McGraw Hill?</p>

<p>McGraw Hill is easier than the actual thing. Mixed in with PR and the Red Book, it’s a good book for someone who’s taking the ACT for the first time, though, because it’s formatted like the ACT and the questions are just like the ones on the ACT.</p>
