MBA Entrance Exam

You should go for TIME material. It will help you surely. And the most important are the Mocks. So, you have an option of going for AIMCAT, the mock series provided by TIME.

You can look for ISM, Dhanbad. It accepts CMAT Score and is a public b-school.

Indian School of Mines University, Dhanbad Sydenham Institute of Management Studies, Research and Entrepreneurship Education (SIMSREE), Mumbai These two are public b-schools accepting CMAT scores.

I heard, 1 year executive programme there is decent. I am not sure about the regular programme. Check with a current student there.
All the best.

I would suggest to go for the trusted ones namely IMS, TIME and Career Launcher. Just ask around about the best of their branches in Bangalore.

It totally depends on the options you have. If you are willing to write CAT again, then I would suggest you to give one more shot. If not, then you can go for colleges mentioned by others. All the best.

The opportunity associated with agriculture business is very limited nowadays. But, the campus you opted for is very good CCS NIAM is a good campus for your post graduate diploma program. The education standard of this campus is very excellent and the students are getting Placement in the expected range. Also, this campus students has very good market value because of the campus brand name. So, I suggest you to go ahead with this campus but not with this course.

If you are looking for IITs, it's possible for you to get admission easily.
Since, you have a good record so far. But, if you look into IIMs, the chances are limited and educational standards are also very difficult and different. With this score, you can expect call from:
1.IIT Kanpur
2.IIT Gandhinagar
3.IIT Madras
etc. The career opportunities are excellent if you go for above campuses. So, I suggest you to go with the above colleges in mind.
