Math GRE: Calculus Textbooks - is Spivak + Stewart + Rudin sufficient?
Recently, I splurged and spent $1000 in math textbooks in preparation for the Mathematics GRE subject test. So far, in terms of calculus books, I have purchased Spivak, Stewart, and Baby Rudin. Is this sufficient preparation for the Math GRE or do I need to get my hands on Apostol? FYI: I am extremely familiar with the univariate calculus and real analysis material. Multivariate, not so much.
