Hello Thilakavathy, 

A good MBA college will not enroll a student with evan a single backlog in graduation.

So you have received a call letter while having 2  backlog, I feel that doing MBA from such institution is not at all worth, it can be wastage of money and time.

I advise you to, first clear your back logs, take a year drop and prepare for MBA entrance exam nxt year. 

Hope this helps  Thank You 

All the best
