I haven't taken a real math class since high school (AP Calc. AB). I scored 720 on the GMAT, 45Q, 44V. My quant score was 66%, and I realize that this will be the #1 application issue.
I've had two careers since graduating. One was building library research databases for a HYP school, and then I started teaching humanities at a private school. My MA is in History, my BA in Anthropology. Besides being a weird and untraditional applicant, I have virtually no quant experience in my job.
Since I really don't think retaking the GMAT at this point will up my quant score significantly, what online extension courses would be best for someone in my situation? I need to prove to schools I can handle the quantitative rigor of b-school, but really can't afford to take more than two this summer.
