What will be the criteria for jee advanced droppers of 2021 who appeared there 12th in 2020 but couldn't get above 75 percent?Will it be the same despite of the year we are dropping?

Dear student,

Till 2019, 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, but this is only for this year.

Now if you have passed your class 12th in 2020 amd want a drop, then there is no surety that this class 12th passing criteria relaxation will remain. It can be retained or removed also. But still there is no official release for this for coming next year.
So, you are only left with one attempt remaining in jee advanced and suppose next year the class 12th 75% criteria once again comes to picture then, it will create problematic situation for you if you will not appear once again for class 12th. So my advice is - appear once again for class 12th exams and secure more than 75% to remain on safe side.
