Guys, thank you so much for your reply.
Rich, I've been studying for a few month, but not systematic: I could do nothing maybe for a week or two, and then in another week study around 6 hours a day. I guess this is a problem. I used official guides, and Manhattan study guides for separate sections, also for the last exam I used Kaplan study guide for the hardest verbal question, and I was doing not bad on problem sets (60 % average depending on the section). My weakest section is RC, and one of my mistakes is that during my recent studies I didn't spend much time on it, because I was thinking to practice more SC and CR, thinking that I would have more chances to increase my verbal score that way. On practice tests I did 630 (Q48, V28) and 710 (Q50, V36).
I am planning to apply CBS, Haas, IE MBA and Duke MBA. As the schools are among top, I'm considering to retake the exam. I am planning to apply this year, for round 2. Only this time I want to follow one strict strategy, right for me, because after last exam I am sure that I am doing something completely wrong.
My profile is this: +5 years of middle managerial experience in retail (Inditex), 1 year experience as a freelancer in business data analysis
Undergraduate GPA 3.6 (Economics)
2 MS degrees (Political Science, Finance)
Would appreciate if you could evaluate my chances and also advise me what to concentrate on, because it's left not much time.
Thanks again)
