West Bengal Board Class 12 Mathematics Syllabus 2022-23
West Bengal Board (WBBPE, WBCHSE & WBBSE)
Mathematics is named as universal language. An equation or an expression written using notation are often read and understood by anyone across the world. West Bengal Council of upper education announced the Syllabus 2022-23 for sophistication 12^{th}. Candidates can check their Syllabus through wbchse.nic.in. WBCHSE conducting HS Board Exam for state and personal schools.
West Bengal Board Class 12 Maths Syllabus is prescribed by the West Bengal Council of upper education, commonly called as WBCHSE. The board was formed during the year 1975 and focuses on establishing quality higher education within the state of West Bengal.
