hey dear you are a general category student ,  you will not be able to get any NIT or IIIT at this rank but don’t loose hope , NIT or IIIT are not the end of life ,their are many private colleges which gives admission on the basis of JEE mains score so you can try for them like

JAYPEE NOIDA 
UIET CHANDIGARH
UPES DEHRADUN

LPU 

Galgotia University

or many state colleges.

good luck
