McGraw-Hill's SAT

I brought home from the library a couple dozen 2009 SAT preparation books for my daughter to choose from as she gets ready to take the SAT in Oct. She just finished Math B and wants to take the Math part of the SAT ASAP while the material is fresh in her head. Her first reaction to this book was, "Ewwwwww! McGraw Hill writes my textbooks! I definately don't want that one!"...but after she reviewed a couple chapters in the other books, she chose this one to buy. The difference that I noticed is that this one offers a couple pages of material to read, then a page of questions about the concepts presented, and then a page of problems to solve using those concepts. The next couple pages explain the correct answers. Sometimes my daughter had trouble with understanding the correct answer to a question. All but one time when she asked for my help, it was because of a typo. Interestingly, the 2010 and 2009 editions had the same typos. I saw no differences between the two editions except the covers, though I did not fully compare them. I have read at several websites that recent editions of SAT preparation books are practically the same as current editions. I insisted on her using the most recent edition because I wanted to be sure she didn't miss an important change. I haven't noticed any changes at all. My daughter took the math sections of a practice SAT before she started using this book. She is spending a week on each chapter. She took a practice SAT after using 2 of the 6 math chapters. Her score went up 100 points!
