Exam

JEE Main 2020 Cutoff is the minimum score necessary to clear the examination. NTA will declare the JEE Main Cutoff in the last week of April, after the result declaration in 2020. The cutoff for General category was 81, 49 for OBC-NCL, 32 for SC, 27 for ST, and 1 for PWD in the previous year. So you have to wait for few weeks and hope for the best.

The last year closing rank in VNIT Nagpur in Mechanical Engineering was 15643 in General (Neutral) category under home state quota. Hence keeping the last year of trends in consideration you have to score above 98.5 percentile in JEE Main, if belongs to general category.

A lot depends on graduation specialisation. Class 10th marks are of concern. If you get the interview call, prepare well for it. You must showcase some achievements apart from academics and must have full knowledge about it as they will ask you in detail about it. Apart from that do maintain polite behaviour as there are people from the Organisational Behaviour area taking the interview. Make sure your answers are logical and have proof or fact attached to it. I think with this you can definitely crack any IIM.
But before that, try to score as high as possible and consistency of practicing all 3 sections daily is the key to that
