I have almost spent a month (quality-wise, quantity-wise almost 2 months) with the Kaplan
GMAT Premier and now after giving the pre-test I have an idea that I need to revise my Maths fundamentals in certain areas (such as C&P, Stats, Number Properties, etc.) thoroughly and practice a lot. Now my question is should I go ahead with purchasing the MGMAT Quant Guides package or this forum's Math book should suffice as far as the concepts/strategies go?
Any guidance/tips will be appreciated. I am targeting to be done with the Quant topics this month and give another test after it to gauge progress.
P.S. Please forgive my ignorance in case this has been asked before as I was not able to find anything similar through a forum search.
Thanks for the help!
