Hello Kanhaiya.

See the marks u have score is not good enough for u to bag a seat in the good IITs for pursuing higher studies in the field of ur interest but it might be sufficient for the NITs for ur MTECH career. About getting PSUs , u might not be able to fetch the good job providers.

I m providing u a link of college and PSU predictor for ur help.
