Hi

This year those who had qualified JEE main 2020 but couldn't appear in JEE advanced 2020 because they had got covid positive  are eligible for directly appearing in JEE advanced 2021 examination without appearing in JEE mains 2021 as per the page number 23  of Information Bulletin released for jee 2021.

But if you are someone who had appeared in jee advanced 2020 or had missed it for any reason other than being covid positive then you'll have to qualify JEE main 2021 examination again in order to be eligible for JEE advanced 2020. In that case,to help you further,
