With a rank of 38k, it is next to impossible to make a Government Engineering College possible and moreover if you are asking for any College for studying engineering, then it is can only happen in some private college under the WBJEE.
You can obviously go for private engineering colleges which are in abundance in West Bengal these days, moreover they are having the facility of management quota where more the hard cash you pay, the better gets the chance to secure a seat and with this you can get a seat in a worthy private engineering college.
This kind of seat reservation with money is not exercised in any Government Engineering College under WBJEE. There when you get a seat for your name you will obviously have the choice of branch. Then see if you are having an opening for CSE.
