greenandwise: You're absolutely right in mentioning the number of variables associated with your performance on the GMAT. Nevertheless, the bottomline is that if I didn't clock it - there must be something missing somewhere. The problem of identifying this gets more difficult when the cause is so intangible;
In my practice tests, I was consistently scoring between 40 and 44 on the verbal; I completely solved the OG, maintained an
error log and reviewed it religiously. So, I can safely infer that I was not lacking in concepts. It must have been the stamina factor.
I'm taking it easy for a couple of weeks. In the process of "unlearning" so that I may start with the practice tests and not remember the questions when I see them. I plan to read extensively over the next couple of weeks (had been neglecting doing that much during my GMAT preps) and then perhaps start with the OG all over again. For Quant, I plan to keep visiting the fourm, take the challenges and revisit Kaplan.
Caspace: I believe your reason for retaking the test is the disparity between your Verbal and Quant percentile. I would suggest you do the following for Quant:
1) Finish Kaplan - their level of difficulty is most indicative of the actual test
2) Start with Kaplan 800 - some see this book as a collection of the toughest problems in Kaplan's other resources, but there are some good drills, especially on DS.
3) Keep visiting the GMAT club.
Good luck, folks!
