Bests & Worsts Reviews from Amazon

I am a private math tutor and author of the Ultimate Guide to the Math ACT. I gave this book five stars because it has the best practice tests. However the content is identical to previous editions, even the page numbers have not changed! The only difference is that there are two additional practice tests included here (one I recognize as the test from December 2008). The bottom line is that you get a better value by spending $21.50 for five practice tests in this third edition versus spending $20 for the first three practice tests in the earlier editions (Amazon prices as of 8/25/11). An even better deal is to scroll up this page to the box called "Formats" in orange letters. Click on the Paperback link and get the book without the CD. The material on the CD is not very helpful and getting just the paperback will save you a few dollars. UPDATE AS OF MAY 4, 2013: Amazon has made it slightly more difficult to find the book without the CD. Scroll up the page to where it says "Formats" in orange letters. Then click on the plus sign to the left of the "Paperback" link to expand it. Then click on the link that says "Paperback, September 6, 2011." UPDATE AS OF JANUARY 2014: Amazon is pricing the book with the CD to be 42 cents less than the book without the CD. No idea why that would happen. UPDATE AS OF APRIL 2014: Amazon no longer sells the book without the CD, so the instructions above regarding formats no longer applies. The book without the CD can be purchased on the Amazon web site but only through third parties.
