Hi TakeGMAT team,

I took the GMAT a week ago and scored a cool 750!

So, I guess my preparation ends here.

I want to thank this website and the TakeGMAT team for offering me continued challenges in the form of good questions. Solving the questions posed by you, to my best of understanding, always boosted my confidence, although the lack of “official” answers and explanations often led me to other websites/forums. But then, this was “My” forum, and so I kept returning back for more and more challenges.

I will not be a regular visitor to this forum anymore, but I am still available on my email id should anyone need my inputs on anything – a question’s answer or explanation, or on any other GMAT related stuff.

I am now in the phase of deciding on the schools I will be applying to. Let us see what’s in store for me.

As a suggestion for this site – I would like TakeGMAT.com to transform its format from quizzical to a real forum-like, where in discussions between members are a common practice. I often think no member’s answers should be accepted without explanations. But that’s just my opinion.
Thank you again for the continued patronage. I hope I have been a good member and author.

I wish all members best of luck!
