In India few Business Schools offering MBA in Agri Business. Like IIM A, SIIB and Others. IIM A admission through CAT & SIIB Admission though SNAP Test. You can take CAT Exam and score very high percentile then have a chance to get good Management Institutes.

Please specify the name of the college. Mostly, for all the colleges, admissions are closed for Masters programme. The session has already started.

Evening/distance/online engineering courses are not valid anymore as per the latest supreme court verdict, hence I would recommend you to join a regular B.Tech course for better career prospects.
