Hello,

You didn't mention any examination name here. But i assume that you said about JEE Mains examination March attempt 2021.

So it's quite difficult to tell you proper percentile by knowing your marks only. But you got 128, so your percentile may be between 97 to 98 percentile. And your rank is probably 17000 to 16000. So it's a assuming details from your marks. I'll provide you a link below you can check it for which rank you have most probably that's you will know

Infact by this rank you can get good college. Infact you can gey NITs. But which college you get particularly if you want to know then go check the another link below
