With this score getting PSU is hard.But as you are from reserved category you have a chance for IITs.But you will surely get Nits. Even you can check your possibility at careers360 college predictor section. Best of luck and Congratulation for your good result.

Hello Candidate,
As per viewing previous year cutoffs you can get most of PSU.
Generally for SC candidate score required around 50 and above for most of PSUs as per previous year trends.
You are eligible for most of PSU and IITs through your score.
