Hi Dipesh you should make it clear about which exam you are refrerring to if we talk about NEET then you need to have a minimum of 50% aggregate in the Science stream (Physics, Chemistry, Biology/Biotechnology) if you belong to the unreserved category and 40% if you belong to the reserved categories.If we talk about JEE then you should have 75% marks in aggregrate for general category.For any other courses like BA or BCOM you need atleast 50% marks.My advise would be to you should give the Improvement exam if you wish to. It is better if you do. It will help in avoiding problems at the time of submitting applications and giving entrance exams.
Hope it helps.
