Dear Aspirant, scoring 82% is good.  If you scored this in PCM then you are now eligible for JEE Mains and Advance , if you qualify these 2 competitive exams and scored the cutoff marks, you will get IIT and NIT. Besides these, there are many other good college's.

If you scored this in commerce, you can think of these programmes for good opportunities-

BBA finance

CA or CS

Psychology

I hope this information is useful.

Thank you
