Dear student,

Now till last year, there was a class 12th eligibility criteria that students must have to pass their class 12 with 75% aggregate marks and it was mandatory till 2019.
But, this year (2020) due to this covid-19 pandemic the class 12th passing eligibility criteria has been given a relaxation, and now you just have to pass your class 12th exam and there is no such criteria this year that you must secure 75% in a class 12th board exams.

But there is no offical news that this relaxation will continue in 2021. It may be possible that after the pandemic situation gets controlled, e class 12th 75% passing eligibility criteria will again come to picture and this relaxation will be scrapped away.
So, just to remain on safer side secure more than 75% in class 12th boards seriously.
