Hey dear

Congratulations!! You have done great.
Kalyani Government Engineering college is one the best colleges in West Bengal. It is a bit difficult to get a seat in that college. Since, you have a category rank as well, that might help you. You could possibly get branches like Mechanical and civil in this college, but not the top branches. You should also refer to  the college predictor link to get a clear idea-

I hope this helps you. All the best!!
