My Strategy was as follows:

MGMAT Course Oct-Dec (3 practice exams during course, and course homeword for the Official Quant and Verbal Guides)

Jan-Feb:
EVERY Math problem in OG 11th, including a thorough analysis of the answer explanations. I did the problems I got wrong, and was unsure of TWICE.

SOME of the verbal problems in OG 11th, including a thorough analysis of the answer explanations.

I logged all my answers and times.

Feb:
Four exams, one a week (2 MGMAT exams 740&700, and 2 GMATPrep exams 680&710). Reviewed the MGMAT exams well. Less on the GMATPrep because they don't have explanations and I found myself getting frustrated.

March 3rd: Exam @ 650

Next exam April 3rd

I was planning on going through more OG problems, focusing a bit more on the verbal but not forget the math. Also, taking 4 more practice tests (again 2 MGMAT and 2 GMATPrep)

I don't know why I scored the lowest on the actual test. I felt confident going in.

During the exam I was unable to eliminate most choices. I found myself stuck between two or three choices more often than in practice.

For sentence correction, I had a much more difficult time finding the splits. For example, in practice I often found that once I found a split or two, I was able to eliminate at least 3 choices. During the exam, I thought there were less obvious splits. Could be in my head.

For reading comprehension, I felt like the passage was not sinking in. I was reading but not retaining, which made the questions more difficult.

As for critical reasoning, I always performed well on that, and unfortunetly I can not tell if I did well on the test on CR because you can't see what you got wrong.

Thanks for your input. I plan on studying verbal AND math during the comming weeks. I think in the end, what happened, was when the answers did not "jump out" at me, I did not have study skills to fall back on.
