Hello Vijendhar,

   Firstly, Congratulations for your score.GATE results are heavily dependent on 
1. Difficulty level of Question Paper
2. No of people appearing.

With this score,you can easily get an admission into almost all the NITs and there is a possibility of getting into some IITs as well. You can also try for PSUs. There is some chance left for you as you come under OBC category. Since the paper is bit easy this year, I think the chances of you getting a PSU is low. But you can definitely try for getting an admission into NITs or IITs.Here, Iam providing the link where you can get the information regarding the cut-offs for various IITs and NITs.
