So I have been lurking here, and wanted to give back and tell my story.
About September-October I was unsure of my job stability prospects, and as such bean studying for the GMAT. I read all of the Math
MGMAT books, and did all the practice problem. I did this slowly, and more or less on the weekends. As it became clear that my job was stable I slowed down. At the end of December I scheduled my exam for January 24th. I took the first practice, a
MGMAT and got a 650.
My goal was a minimum of 720 initially, and 730 later on.
I kept retaking the exams and focusing on what I got wrong, eventually it went from not knowing to making careless mistakes and my score stabilized around the 710-730 range (on
Manhattan GMAT and Kaplan exams).
I did not really do any Verbal studying, but used logic and common sense, and usually got 90%+ on it. Math I was stuck on 80% are, sometimes a bit more, sometimes a bit less.
The 2 practice GMATs one taken 6 days before the exam (and before 6 days of continual studying) were 740 and 730 (the day before the actual GMAT).
Both had a similar math score, with only verbal varying.
I took the GMAT today and got a 710, with a 48 quant and 39 verbal. I aiming for top 10, so that is just a bit below what I need, I will be retaking it.
I scored very similar to my practice math, but just slightly worse then practice verbal.
One thing I found out was Princeton Review was more or less useless for anything 700+, their practice exams were easy, and graded on a weird scale (4 wrong in each section led to a sub 700 score). The MGMATs had Verbal and Math in my opinion that was slightly harder but was good to know, and very accurate scoring. Kaplan was a little bit worse then Manhattan.
Also please ask if you need anything else to make this more helpful.
