Hi Abhishek,

AIMA, the conducting body of MAT exam doesn't release the cutoff. As MAT score is accepted by more than 600 B-schools, every B-school releases its own MAT cutoff for its admission process. The top B-schools in the list of MAT participating institutes have a very high cutoff. XIME Bangalore's cutoff is around 700, IPE Hyderabad 650, IFIM Bangalore 600, etc. You need to check with the individual B-schools if you meet their cutoff criterion. if you qualify the cutoff of a particular institute, you can simply visit the official website of that institute and apply online for the admission process. 

Good luck.
