agree...totally depends on u if a class is right 4 u...i wud start wit books and tests and see what works, then go 4 a class if u r not getting ur hopeful score. classes can be v. good if u need discipline and like 2 learn from a teacher instead of books.
i got cracking the gmat from princeton review and their verbal/math workbooks. very good. also get official book from
www.mba.com and the gmatprep tests. must get those 4 ur prep.
all the best.
