Hey! With a WBJEE GMR of 33652 and being in the OBC-B category, getting a core branch like CSE/ECE in top government colleges is very tough. But still, you have chances in some government engineering colleges in the later rounds (especially 3rd or mop-up).

You can try for colleges like:

Government College of Engineering and Leather Technology (non-core branches)

Government College of Ceramic Technology

Some seats in Kalyani Government Engineering College (in lower demand branches)

Regional Engineering Colleges or other state-aided universities (but mostly in non-core departments).

My suggestion: Keep patience till the last rounds because sometimes seats do open up for OBC-B. Also, keep backup options in private colleges or through management quota if you want a specific branch.
