Dear Aspirant,

First of all congratulations for getting such a good marks, Now considering your Jee main September marks your expected percentile and rank may be:

Your Overall Percentile is: 98.83 - 99.03

Your Predicted Rank is: 8799 - 10449

As this is similar to your previous percentile,so best of two will be taken for final ranking.

Now in this rank/percentile and by applying female reservation you have good chances of getting ECE branch in top Nits but there are less chances for CSE branch. But you may get CSE branch too in your state Nit(if any) using your State quota.

You can go through this link to get an idea about previous cut offs for NIts:
