You can still score more marks in CMAT, if you start preparing from now. With your profile, I would suggest you to try getting more marks in CMAT. I also suggest you to apply for MAT exam. With 120 in CMAT and your profile, you may find it very difficult to enter decent institutions.

Kirloskar Institute, Singhad Institute, Balaji Institute are known B-Schools accepting CMAT/MAT scores.

While preparing for CMAT, you should give equal importance to all the topics. Try to have a glance at each and every topic because we cannot predict from where things will come. You should study every topic thoroughly. You can get some inner sight after solving a couple of previous years question papers.

Your NMAT score is very low. You should try for SIMSREE, KJ Somaiya or Welingkar to pursue MMS or PGDM.

MAT cutoff is approximately 600 and
CMAT cutoff is approximately 210.
Hostel fee per year will be around Rs 72,000.

Not too sure about specific cut-offs for PGDM. I am an MMS student.

I am an MMS student. No idea about PGDM cut-offs.
