Vijay,

I think your problem was not necessarily quantity or quality of practice- it was more about your state of mind.

Getting a 700+ in GMATPrep and a 600+ in Kaplan certainly proves that you're a strong 700+ candidate. And you seem to have used all the right resources for preparation (OG, GMATPrep software)

I would suggest you work more on keeping yourself in a cool and calm state of mind. I've had friends who've taken the GMAT who were either TOO relaxed or just TOO nervous when they took it. Either extremety will hinder your performance.

Personally, I was relaxed, not nervous at all. It was exciting for me to take the test. I think that helped me. I went from a 620 in my first GMATPrep test to a 710 on the actual one.

So ensure that you're in the right frame of mind for the test. Don't get too worked up about solving loads of material. There IS such a thing as over-preparing. If anything, I'd suggest you pre-pone the test if possible!

All the best!

PS: Looking at your sectional scores- you may want to work a bit harder at your Verbal. Solve 1000SC and OG-Verbal/OG11. And spend at least 2-3 mins analyzing every single question. That, combined with your excellent quant, should get you well past 700.

And no, GMAC will NOT provide you with a list of right/wrong answers. If they did, the whole world would know their formulae, and the GMAT's control over testing practice would be destroyed! That's why Princeton and Kaplan et all do NOT give you the same kind of accuracy GMATPrep does.

dear Vijay,

Wildrebel is correct.
You certainly deserve a better score.
What went wrong? were you nervous or overexcited?
Anyways since you couldnt figure out the reason it will be foolish to ask this question again.
OK

i can tell you some reasons why score fall.

** if you mess with earlier or and last few questions
( yeah i know 8 myth but still it could be one of the reason )

** if you consequetively answer wrong questions
eg.say you answer item no. 9 10 11 & 12 wrong then,,,
your score may fall dramatically (by hundred sometimes.!!)

**case may be this( the above cases) might not have happened with you during your practise tests.

My suggestion
* keep you head cool
* & make sure you dont get wrong answers in series.
next time
all the best
