Thanks, bb: that's relieving! Actually, my status appears now as "Taken - scores reportable", although I cannot access them probably because AWA was not been reviewed and scored yet.
I did well in the exam, getting an unofficial score of 710, 92% percentil (47Q, 40V). I found the math part very similar to GMATPREP both in types of exercises and in their difficulty. The verbal part seemed harder than the GMATPREP, specially sentence correction and a long management passage with many acronyms that involved going up and down in the lines to retrieve what each was refering to. Thus, the relatively low score in Verbal, unbalanced with Quant. Anyway, I won't retest. 710 is enough for major business schools and extra push for getting in should come from the rest of the application
Congratulations!
710 is plenty - if you are targeting top 20, the gmat score is not the decision maker there. It is nice to have a 99th percentile, but with the amount of time it will take to get there (for anyone really), better to invest your efforts elsewhere - essays, recommendations, resume, activities, research school, etc.
