Hello hemant,

You should score 150+ marks in jee mains and you can easily get branches like electeical but to get computer science you need to score 200+.

Moreover class 12th marks have no weightage from 2017 onwards. You just need to scorw greater than 75% in class 12 boards.

So the answer is yes there is a minimum percentage of 75% to get admission.

Hope it helps
