Dear Aspirant

If your board score is less than 75% then you are not eligible for NITs in 2021. The removal of the +2 marks is only applicable for this year, i.e., 2020.

However, you can apply for the improvement in the +2 marks, and then you can try to score more than 75% and prepare for the JEE along +2 preparation.

Hope this helps, THank you.

For more details about improvement check out the official website of the respective board.
