MBA/PGDM

Christ University, Jain University, Indus Business Academy and Thiagarajar School of Management are some of the good colleges for MBA based on MAT score. Again it differs from specialisation you prefer.
All the best.

I would recommend UEM-Kolkata as per your location as this is a private college and many have their own exam for qualification and the University of Engineering and Management provides the best infrastructure with good placement assistance with low fee structure.

Hi Divya,

As per me, you should opt for MBA.

Hi,
Abroad is a vast term. It is good if you could mention the country. You may alternatively check ranking tables like QS Ranking. Harvard, INSEAD, London Business School, etc. are some of the best institutes. The top universities have excellent career assistance service, please understand its not on campus placement. They will only help you network with potential employers. You may check university websites for all these details.

There are universities like Thompson Rivers and Vancouver Island University which do not require GMAT. You may check their websites for details.

MBA stands for Master of Business Administration. By opting MBA, a person can make his career in the management field after the completion of the degree. You need to have good skills to get a high salary package.

Well, it depends upon your interest. Either you can opt M.Com or MBA in Finance. All depends upon you.
