Hi Adarsh!

First of all, a very hearty congratulations on your score! 

To find out whether you will get admission in NIT or not and to get an idea on the streams available, you have to follow two steps:
1) First of all, you can use the rank predictor provided by Careers360 to predict your rank for 85.179 percentile through the following link:

2) Once you receive the predicted rank, you can find out the predicted college with respect to your preferences using the college predictor provided by Careers360 through the following link:

After following the above two steps, I am expecting that you have gotten a rough estimate as to whether you will get the seat or not.
