The admission and fee criteria varies college wise like if you want to go for NITs then it accepts Jee main score and the fee would be lesser than any private institute and in case you want to get admission in any private college like VIT then it conducts its own entrance test (VITEEE) and 1 year fee would be in Lacs. So kindly be specific with the college name from where you want to pursue your B.Tech course.

Good Luck!!!
