GMAT

Hi,
Any top ranked university will ask for the GMAT but few options may be available. You may check for graduate certificate programs or PG Diploma programs.

CMAT will do. Rest, you can check on www.ibsindia.org for more details.

Yes, shortlist based on scores and then GD - PI.

You should start preparing for GMAT right now. It takes a lot of time for practicing and if you are planning MBA abroad. Although GMAT score is my sole determinant for admission, you need to have 730+ score if you want to get admission into a good institute
A 700 GMAT score puts a test taker in the 89th percentile of those who have taken the exam. That means only 11% of those who sit for the GMAT have a score of 700 or above. Hence you need to work and practice hard, take mock test, etc.

In Globsyn Business School you require a minimum of 50 percentile for both the entrance exams.

Hi Sonali,
Not at all, GMAT is basically required for MBA programs. It's not required for each and every Master's degree course abroad.

You don't have any chance of getting admission in a good college. Stanford's cut-off is 740 and Wharton's is 728.
However, if your aim is just to get MBA at any cost then IIPM, Manav Rachna and Manav Bharti are the kind of institutes which exist in the USA who can't provide you placements, but they badly need students so you can search and apply for such B or C category institutes.
