Hello prabshan, thanks for your question.
What does your undergraduate GPA equate to in a US system?
I think you already know that you are part of a highly competitive demographic in the MBA applicant pool. Your 630 GMAT score is going to be a significant obstacle in gaining admission to top US programs.
On the other hand, you seem to have some good fodder for interesting essays. Demonstrating your leadership performance and potential will have be the strength of your application.
If you are aiming for top US programs, I’d recommend retaking the GMAT.
I hope this helps!
Best of luck,
