With 146 marks in NMAT, unfortunately, you don't have good options. NMAT is not accepted by any top college apart from NMIMS and its sister schools in Bangalore and Hyderabad. So, you're advised to re-attempt it next year. If you are looking for tier-3 options and are okay with the cadre then you may opt for L.M.Thapar, MISB Bocconi, Woxsen, IBS, Shiv Nadar University, UPES College of Business Management and Economic Studies, Alliance School Of Business, SRM University- Chennai, GITAM University-Hyderabad, BML Munjal-Gurgaon to name a few.

Goa Institute of Management (GIM) accepts XAT GMAT and CMAT apart from CAT scores. A score around 85-90 percentile in CAT is good enough to get a call from GIM. Some colleges accepting NMAT scores are L.M.Thapar, MISB Bocconi, Woxsen, IBS, Shiv Nadar University, UPES College of Business Management and Economic Studies, Alliance School Of Business, XIM-Bhubaneshwar, apart from Narsee Monjee colleges.

There's no harm in applying and trying your luck there.

Hello!
Unfortunately, there is no good and reputed B-school anywhere in India where one can expect getting admission with that score in the NMAT exam. And the ones you might get won't simply be worth enough to pursue MBA; a total waste of B.O.Th time (2 years) as well as money (in Lacs). I suggest you to either reappear for NMAT (or other exams as per your wish) next year or focus on the other upcoming exams like MAH-MBA CET and MAT in case you want to do start MBA this year itself. Good luck!

Hello!
Unfortunately, with that score in the NMAT exam, there is not even a decent B-school from which one can expect getting admission. The cutoff of all good B-schools via NMAT is generally 190 and above. Thus, there is no point in pursuing MBA from a below-average B-school and wasting B.O.Th your precious time (2 years) and money. I suggest you to either reappear for NMAT (and other exams if you wish) next year or focus on the upcoming exams like CET and MAT. Good luck!

Hi,
