i just took the gmat a second time. first time i scored a 610 (42nd percentile in quant and 84th percentile in verbal). i decided to retake it a month later and did nothing but study quant. on my second attempt i scored a 640 (33rd percentile quant

and 97th percentile in verbal). So after dedicating about 100 hours over a month, my quant score actually decreased!! I've decided to wait and take it once more but only once I am consistently scoring in the 60th percentile and up range in quant on gmat prep. I think my main disadvantage in quant is that i never solidified my math skills as a youngster so at age 25 it is hard to relearn those concepts and have them stick. I think I truly need to start at the basics and work with that approach. i don't even know how i passed calculus in undergrad...truly pathetic gmat quant score...it is extremely frustrating to put in a lot of time and effort only to see your score decrease! any tips on the best way to study for quant? i just purchased a few quant books and did a lot of practice problems and did like 10 gmatprep tests, which is why i think i've practically mastered the verbal, as a result of seeing the types of questions over and over.
questions about grad schools - let's say that hypothetically i get my quant score up to the 60-70th percentile range and my gmat goes above 700, how will schools view that?
