I just Beat The GMAT!

Hi, I have been studying for GMAT for sometime now, almost 3 months on and off, on mostly, I think i am in my third month now. my first CAT was 540 , second was 500, my first diagnostic which i struggled with interms of time and focus was a mere 400 something. I had been studying with Kaplan premier, after my second kaplan CAT (500), i decided to take a break , refocus and reorganize, i started reading the blogs , study strategies, etc, various posts, and comments on this website, I bought kaplan math workbook to go thorough the math basics again, also bought MAnhattan SC and kaplan 800, just started doing problems from OG 13. I fell my math is better now, I plan on taking GMAT mid Novemeber, so I have a month to really work on it. I wanted to get some suggestions, in terms, what I could do this month to really work on it. I dont plan on taking any more CATS at this point, I believe I want to go through as much of the OG 13 as possible, then I'll do a Kaplan CAT.

I just wanted to get some suggestions from you guys. I understand GMAT is not about how much practice problems one can do but how one thinks about and approaches a problem. Your comments and suggestions would be appreicated
