Can I get some recommendations for CS textbooks to study for the CS GRE? Note that I am already fluent in C++ and Python (and getting better at Haskell), so I don't need hand-holding in learning the very basics... however, I do need to review the standard theory. For example, if the GRE asks: "What are the fundamental elements of OO?" I'm actually not sure what the answer is. (There's a difference between using an OO language, and talking about the theory behind it. In garden-variety programming we never talk about the theory.) I assume that any textbook is going to include the basics---I can skim through those parts. But I would be curious if there is a textbook that quickly gets into the deep stuff (and is particularly relevant to the GRE). Thanks, J
