Yes Rahul, with your 471 scores you have a very good chance of getting to some of the PSU's like ONGC. If you can tell me your normalized gate marks then it will also help a lot in finding out the PSU's where you stand a good chance by comparing your marks to last year cut-off because of many of the PSU's real normalized marks (out of 100) as their cut-off instead of GATE score

I am also giving you the GATE Cutoff list please check the PSU Cutoff list through the given link:

Feel free to ask if you have any more queries. All the best!!
