This ACT review book contains important tactics for approaching the test, but breaks it down into manageable parts. You could just spend a few hours with this book, and get something out of it, or you could go through it thoroughly and get more out of it. Written in clear, memorable language. I use it to help students do test prep. They say it's better to take paper practice tests, since they still do the test on paper, so it suits that purpose as well.

I am a high school student who is getting ready to take the ACT for the first time in a couple months. This book has really helped me get a feel for the sections on the ACT as well as what my weakest spots are. Kaplan's ACT 2008 is easy to understand and even enjoyable - I recommend it!
