On Question asked by student community
Hello dear candidate,
You cannot get admission later through WBJEE counselling for that year if you missed the decentralized counselling as it is the official last chance to get admission through WBJEE.
Only chance left is by management quota but the fees are very high.
The Mop Round for WBJEE B.Tech counselling in 2025 would be held in late 2025, after the main counselling and allotment rounds have concluded. You can also refer to the official website of WBJEE for further information or detailed information.
Hello,
With a rank of 10536 in WBJEE 2025, you would have a chance in the government engineering colleges, but you have to choose less popular branches where the competition is less or not crowded. Still, your chances of admission depend on factors like specific colleges, cutoffs, the demand of this college, and the location of this college.
I hope it will clear your query!!
With a rank of 41200 at WBJEE, taking Techno Main Electrical is most appropriate option as it's a direct admission through counseling, while direct admission to CSE at Techno Main or IEM might not be possible or it can come with higher costs. Prioritize getting a confirmed seat through your rank through the standard WBJEE counseling process, as CSE admissions are highly competitive, expensive and typically requires a better rank. You can explore direct admission to CSE in a higher-ranked college if available, but if limited to these options, the confirmed seat in Electrical at Techno Main is a better choice than a unavailable or very expensive direct CSE admission.
With your WBJEE EWS category rank of 2866 and West Bengal domicile, you have a good chance of getting a seat in government engineering colleges like Kalyani Government Engineering College. The final allotment will depend on your preferred branch and seat availability during counseling, so make sure to participate in all rounds.
