hello aspirant,
With 80 percentile in JEE mains, your ST Category Rank will be around 1,80,000 or around 2,00,000. Your CRL Rank will be even much higher. So, looking at the previous year Cutoff for JEE mains for ST Category student, it is difficult for you to get admission in good NIT's like NIT Surat or MNIT Jaipur. However, you can still get some low ranked NIT's or GFTI's under this ST rank.
I would suggest you to follow the JEE mains College predictor tool, to know more about your admission chances in other engineering Colleges (The link is mentioned below).
