So, I've just finished my first round applications, and I have some time to spare before the second round comes along. Although I managed a 720 on the GMAT, my Quantitative grades weren't great in my undergrad.
I thought the best way to use my time now is to do an online course on MBA mathematics, so that I can cement my quantitative basics and also have an alternative transcript if the need arises. I have done my research online and I have the following four options to pick from.
1:
MBA Math($150) :
2:
MBA IQ($195) :
3:
GMAC Essential Prep($200) :
4:
Harvard online courses :
Three Interesting courses here:
->Mathematics for Management - $90
->Quantitative Methods - $150
->Spreadsheet Modelling - $110Which would you recommend for me? If you can think of any better options, please let me know.
Thanks in advance!

PS : I would have included the links, but GMATClub wont let me
