Unfortunately, it's highly unlikely that you can secure admission to the University Institute of Technology with a JEE Mains rank of 398150. According to the University Institute of Technology cutoff for JEE Mains, the minimum rank in the round 1 cutoff is 8605 for BE CSE and the maximum rank in the round 3 cutoff is 95570 for BE Civil Engineering. Hence, your rank is too far from the maximum cutoff which makes it less likely for you to get admission to the college.
