Hi ! You did not mention your home state. Anyway as your percentile is 85, your rank would be above 131,000 so maybe there is no chance to get a NIT college. You should keep focus on your JEE Mains 2nd Phase, which is going to be held next month. Rather than this you can get good state Govt. Engineering college with this percentile.

Hope this will you.

Thank you so much.

Good Luck for Journey Ahead.
