<p>As of now, I have been using PR Cracking the ACT, and McGraw Hill’s ACT 2008. I find that PR Cracking the ACT is a lot easier to use, and it seems to be better quality than McGraw Hill. I also own The Real ACT Prep Guide (Red Book) and plan just to use this book purely for the 3 practice tests after I review the PR book. Cracking the ACT has a lot of good test taking strategies that you wont find in The Real ACT Book because the test writers do not want to give any strategies away because it kind of counter-acts their test.</p>
<p>I hear a lot of good things about 1296 ACT questions, so I’d recommend combining that with Cracking the ACT, and The Real ACT Prep Guide.
Good luck with the test. :)</p>
<p>PR Cracking the ACT is really good-- the practice tests are fairly realistic and the teaching material is good too. I bought the book, used it for like one month, then took the ACT and scored a 33 Composite (36 English, 33 Math, 33 Reading, 30 Science).</p>
