WBCHSE Class 12 Science Syllabus & Marks Distribution!

Every state has its own educational board and the schools associated with it follow the respective syllabus. The education ministry of the West Bengal government is responsible for the conduction of examinations of higher class students of different streams. WBCHSE (West Bengal Council for Higher Secondary Education) was formed to enhance the education system and literacy in West Bengal. This government body is responsible for class 12th final exams, especially. 2023 has nearly 8 lakh students registered under the WBCHSE for the 12th final examination for every stream including Arts, Commerce, and Science.
