I recently took the GMAT and after very little prep I got a 710 (42V, 45Q, 5.5AWA). My only prep consisted of an outdated GMAT prep book which my school's library had for free use online, and I only studied for a couple of weeks. I am certain that I could do better with better materials and with more effort on my part, but I'm wondering if I should bother?
I know that my quant score was a little weak, but perhaps my undergraduate education can supplement that? I go to a large state university and have a 3.9 GPA (finishing a 2 degree, 5 year program in 3 years), in the honors program with a triple major in finance, economics, and managerial economics (with enough accounting electives to take the CPA exam). On top of that I have taken some quantitative classes which I believe demonstrate my ability to handle the coursework of an MBA program: calc 1, 2, 3, linear algebra.
I'm just wondering if it would be worth the additional time and cost to take the GMAT again? I almost feel like my time and money would be better spent on becoming a CPA or CFA.
