Hi everyone, I'm new to the forum and so I haven't had a chance to search through many of the topics so far... I'm wondering which prep book is the best to use to prepare for the test? I'm writing on September 6th and am starting to prepare now.. I wrote one of the practice tests and scored either 610 or 620 (it was a few weeks ago). So, just wondering which book you recommend and why?

Thanks a lot!
