Hello Aspirant,

For this year it does not matter how much you have scored in your 10+2 because according to the latest notification in the wake of COVID-19, from ministry of education, now criteria of 12th percentage has been removed.

Now you have to score good marks only in JEE-Advance to get good colleges. If you want to get into IIST then also you have to crack JEE-Advance with good score.
