It will be quite difficult to get CSE in Normal quota or i can say in any quota.

I am saying all this because if you consider the total number of Students appearing for the exam this year and compare it with your rank, you can see the result.

This year around 35k students appeared for the exam and total seats for the enrollment is around 5K. So, you can see the difference.

Generally CSE got over inside 6k rank only, last year.
