Hey Nishant

You have not mentioned the course you want to take admission in however to take admission in ABM College you need to meet the following criteria:

You need to have passed the intermediate or equivalent examination of a recognized Board / University (and you must have the result, the admit card xerox etc)

2. You need to have scored 45% marks at the +2 level in the subject you want to take admission in.

However if you are talking about Agro Business Management then

You need to have scored a minimum 50% (45%  for reserved category ) in graduation in the following courses - agriculture, animal husbandry, agrochemicals, dairy science, fisheries, food science, forestry, horticulture etc as well as someone from science (including biology background)

However you will need to give atleast one national level exam like CAT, MAT, XAT, CMAT, ATMA & MH-CET.
