Bihar Board Class 11 Maths Syllabus
Bihar Board Class 11 Maths Syllabus

Bihar School Examination Board (BSEB) designs the detailed syllabus of Class 11 Mathematics subject. The board conducts an annual exam for this subject consisting of a theory paper and a practical exam or viva. Class 11 is considered as an important and crucial academic year for students as it prepares them for their higher studies.

A student must invest a lot of time and energy to learn many new things and revise the old concepts learnt in their previous classes. This will prepare them for their educational journey ahead. In fact, all the subjects are important in the class 11. However, some subjects are a little more important as you will need them throughout your life. Maths is one such subject.

The concepts studied and thoroughly practiced in Maths are bound to help students in their career ahead. Moreover, those students who have decided to give the nаtiоnаl level entrаnсe exаms suсh аs the IIT-JEE and NEET will benefit frоm the revisiоn оf the BSEB Class 11 Maths syllabus and the concepts therein.
