Thanks for the congratulations. In response to a couple of requests, I'll debrief.
QUANTITATIVE:
I could have done better, but I imagine that most of us could. I would emphasize using the free GMATPrep Software again and again. Even though some questions will be repetitive over time, you will continue to find new questions. In fact, one of the questions on my test was exactly like a question from the software, only the numbers were changed. On math exams, I make too many careless errors, and in retrospect I can think of a few that handicapped me. But, in general, GMATPrep is free yet invaluable.
VERBAL:
This was my saving grace. My study method for it, however, may not be practical for everyone.
I was an English major in college. And since I am applying to JD/MBA programs, I spent a couple of years preparing for the LSAT, which is very similar to the verbal portion of the GMAT.
The stark reality about the verbal section is that logical reasoning is often a painfully acquired skill. I practiced the LSAT for months before I started to pick up on the modesty of a good answer versus the overstatement of a decoy answer. In general, the logical answer is often the least intuitive. Again, my only concrete recommendation is to practice questions, make mistakes, and try to learn from those many necessary errors.
I hope this helps. If anything needs clarification, please let me know.
