Being from West Bengal Domicile Category as well as General, I dont thik with a Rank of 5715, you'll have fair chances in securing IT, ECE or CSE in any of the Good State Government Institutions with extremely bleak chances in KGEC Kalyani and moderate chances in lower branches at JU,KGEC, Government College of Ceramic Technology, Etc. I would rather advice you to target some of the Good Private Engineering Colleges in WB accepting WBJEE Scorecard like IEM Kolkata, Haldia Institute of Technology, Techno India and Heritage, which definitely have good infrastructure as well as Placements as of now.
