Hello Buddy! Hope you are doing good.

As you had done your 12th in 2020 then you are only eligible for JEE Advance in 2020 and 2021. And in both the year it's not required a minimum % of 75%. Well this year you wasn't able to qualify in the JEE Advance then there's a number of colleges out there which take admission on the basis of JEE Main. So take part in state counselling or private institutes counselling for securing a seat. Hope this will help you.

ALL THE BEST! WORK HARD !!
