Hi there,
Hope you are doing well.
The answer to your question is No.
The minimum aggregate percentage required for SC Category in Class 12th is 65%.
Without this, you won't be allowed to sit for counselling.
Also, the admission for NITs closes at a rank of 9000-10000 for SC Category and your rank is way higher than this. So, you can't expect a seat.
Hope it would help
Thank YOU

Hello dear

As you are saying that your 12 th percentage marks is 64.

Eligibility for admission in nits is that you have to secure atleast 65 % marks or should be in top 20 percentile.

So if you are in top 20 percentile than you can take admission in nit. And with this rank you may get admission in low ranked nits or non core branch in some nits.

So good luck.
