WBCHSE stands for West Bengal Council for Higher Secondary Education. It was in the 1970s when it was established by the West Bengal government under an act of 1975. Kolkata is the headquarter and this council is responsible for the conduction of the class 12th examination. 2023 will nearly have 8 lakhs of students registered under WBCHSE for the 12th final examination. It is situated at Vidyasagar Bhavan, Salt Lake, Kolkata and for more queries, you can reach the officials at 033 – 23374984. In addition to this, for more official information, notices, and circulars, you can visit the official website, wbchse.nic.in.
On 10th June 2022 WBCHSE officially released the exam dates for class 12th. The timetable can be easily accessible on wbchse.nic.in. The exams will commence on March 14 2023 and will last up to March 27, 2022.
