I've read several times people talking about using GRE Math information to help them with the QR part of the test. Did you buy a book or download that 69 page document? Thanks a lot!!
Be aware that some of the questions are in a different format than what is presented on the DAT. On the GRE they have a lot of questions that are presented in two colums and it is your job to determine if column A is greater in value than column B, if they are equal, and so forth. With that in mind, don't get to confused to distraught if you open up a GRE math review book and see such problems. You will NOT encounter that format on the DAT.
