I missed major management entrance exams. What should be my approach now to get selected in the best college?

Hello Akash, All the major MBA entrance exams have been already done. The next important exam would be NMAT (From Oct - Dec) followed by CAT, IIFT, SNAP, XAT, etc. You can prepare well for these exams as you have ample time. You can join some reputed coaching class, if required. All the best.

You can try next year. You can prefer appearing for CAT, XAT, CMAT or GMAT.
