my board Percentage is 58.2% that's good for jee main point of view, how much percentage is compulsory for jee main entrance exam.

Dear student,

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 from this year 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.
That means securing 75% in class 12th boards this year is not mandatory.
So, if you got 58.2 % in your board exams and a good rank in jee mains then you can easily get nits.
And for getting a good nit, your jee mains percentile score must be above 98 percentile.
