See the normal criteriaof board marks for admission through JEE Mains and JEE Advanced into NITs and IITs is as follows:

Candidate must have minimum of 75% in 10+2 science exam from any recognised educational board. But due  to the covid-19 pandemic this criteria has been relaxed.

Now ONLY for the year 2020 the candidates must have a pass marks in their 10+2 exam and the requires cutoff for JEE in respected colleges.

Now If you had enrolled for JEE mains this year you fall under the new category .

If you are trying to give this exam  next year wait for the guidelines ....

Thank you , Hope you got the answer

hey,

i hope you are doing well

from this year percentage criteria is removed that is you are no longer supposed to obtain a minimum aggregate of 75 percent or 65 percent (for reserved category) in your 12th standard in order to get admission in NITs , IITS and GFTIs , you just need a passing certificate of your 12th standard. , if you clear the jee mains exam you will be eligible to appear for JEE advanced as well.

hope this helps!
