macsurf, how did you make most out of GMAT prep? did once each?
please, do each one at least 3 times and review the mistakes thoroughly.
also, before re-taking gmat, do the following:
-70 Brutal SC tests - can be found in the verbal forum
-25 GMAT Club challenges
to improve your math
- Also Sergey_is_cool posted 100 difficult math questions (in .doc format) - it is made sticky and in the math forum
Dont get carried away with your GMAT prep tests - yes, they are closest to the actual, but you might have realised that there will be a few repeat questions, therefore distorting your results.
And actively participate in the forum here at GMAT club!!!
I can understand why you got lower than you expected. I am confident with 1-2 month prep you can easily pull 650+ and wouldn't be surprised if you scored 700+!
See you in the forums!
