I believe that this article addresses the topic pretty well: http://www.physicsgre.com/viewtopic.php?f=13&t=1073
Personally, I found Physics Builder
and the selected problems from the Purple Book
to be quite helpful. Although, I will say that Physics Builder was FAR too easy, and the Purple Book was FAR too hard, they at least provide extra multiple choice problems to practice on. My personal studying consisted of working through Physics Builder, the Purple Book, and all the four practice tests... but we'll see on Nov 19th how much it did me. Good luck finding stuff to study from!!!
