What's the best book to use to prep for the GRE subject test? For Topology, I was going to use the first few chapters of Munkres, and algebra first two chapters of Dummit and Foote. Are these good selections. I planned on working my way through Rudin for Grad school prep, but that seems like overkill for GRE prep. I thought maybe I should use Spivak or Apostol for Calculus....I've heard that apostol exercises will often appear on the exam. However, the apostol book is expensive, so if Spivak is good, I would rather use that book. I would assume that apostol and spivak would also help me review for gre style analysis. What about Number Theory? Finally, how about linear algebra. I've heard that there aren't any good books on linear algebra. If I spent the $300 dollars on apostol...I know that covers some linear, but I don't like the idea of spending that kind of money on a textbook. Anyway, I'd appreciate it if you guys and girls could give me insight on the best books to work through for Gre prep.
