I just Beat The GMAT!

I took GMAT today, and scored 660 (Q49, V31). I am negatively surprised as my scores in GMATPrep were:

G1 (One week ago) - Q50 V40 730
G2 (3 days ago) - Q50 V40 740

One mistake that I committed was taking two tests without reinstalling the software, 2 days before the exam.

G1 Retake - Q48 V 41 710
G2 Retake - Q50 V35 710

Material I used was OG11, OG VR, OG QA, KAP VW, KAP 800 and MAN SC.
During the test, I realized DS was tad difficult compared to that in OG/KAPLAN, while I was underprepared in CR and RC. Moreover, I spent almost 30 minutes doing first 10 questions, one of which was a boldface CR , and got crunched for time towards the end. I was done with Quant 10 minutes before time.

What should I d next ?

Re-installing aint of help in GMAT Prep software.

You have had plenty of material for study. 660 is not a bad score. & GMAT is not the only factor b-schools look for in application. Lot of other factors matter too.

Does re-installing the GMAPT prep software really matters when you want to take the pre p exasm more than couple of times. Can more people weigh in on this. Appreciate it.
