Query: one of the worst books to prepare u for the DAT

I do not recomend this book one bit!, it is full of mistakes and the explantions for the answers are not there. All the sections contain serious error and the phrasing of some questions is vague to say the least. The answers provided for most of the questions is wrong!, and that applies for the science section as well as the math and perceptual ability sections. You are better off taking the test without prepartion than taking it studying for it with this book.
