Hi Sourav, hope you are doing well, with your rank of 80k you can not get any of the core brances like cse, ece, even though your EWS rank is 10121. I suggest you go for some private colleges like lpu so that you can get your desired stream and lpu is also good both in academics as well as placements. To know more about the admissions through jee mains, go through the rank predictor in jee mains, the link for rank predictor is provided below
