Hello Aspirant
You will definitely get a good nit.you have a reservation it helps to get good College for your percentile.
Use this formula to predict the rank:
Rank Formula = (100 - your total score) X 874469 /100.
If you got less than 224000 rank then you are eligible for the JEE advance.

For getting a seat in any nit not considering the branches minimum rank should be under 30k.

If you have any questions further let me know.

Thank you!!!!
