MBA Entrance Exam

You won't get good college with this score. I would suggest you to take admission next year with better score and easier entrance exam like mat CET etc.
Still, if you are very keen to take admission, then go for MITSOB, GIBS, and BIMM.

I guess you mean Top MBA College, not MA college.
XLRI, Jamshedpur.
FMS, Delhi.
SP Jain, Mumbai.
IMI, Delhi.
NMIMS, Mumbai.
JBIMS, Mumbai.
ISB, Hyderabad (I think this is the best of all)
Cutoff for them is as high as IIM
All the best.

Hey any score above 98 percentile is considered very well for MAT exams. Since MAT is considered to be an easy paper compared to other form of entrance, that's why cutoff goes very high.

Yes, you can apply through MAT score. Just go to the link:

Best of luck.

Being an alumni, I would not like to recommend you ITS, PGDM. If you scored 90%, you can opt for colleges like BIMM-Pune, IIRM-Hyderabad, NIBM-Pune, and XIME-Kochi. If you scored 97%, you can chase SIMSREE-Mumbai, PUMBA-Pune, XIME Bangalore, KJSMAIYA, and JBIMS. Choose your area of interest (sales, financial sales, core finance, HR) and then choose the college according to that.

Last year, the closing rank for CUSAT CAT was 1581.

Kindly visit the given link to know about the B-Schools in Kolkata accepting MAT exam scores.

You can appear for NPAT in late months of class 12th. But, you should begin preparing from now. If you are planning to appear for MAT, then you are too early to think about it. You need to be a graduate first.

Hello Mihir,
You can choose to appear for either CET or CMAT to take admission into XIMR. However, the CMAT cut-off will be higher as it's an All-India level exam, and the cut-off will be lower for CET.
