The Central Board of Secondary Education (CBSE) has ended the term-wise exams for classes 9th-12th. This means students would be required to sit for the annual examination at the end of the academic year only. The board released the syllabus according to the annual scheme of assessment only. We have provided below the CBSE Class 11 Biology Syllabus 2022-2023. Students with Biology must follow this latest syllabus while studying the subject. They should carefully note the unit-wise weightage and the prescribed contents to prepare for their CBSE Class 11 Biology Annual Exam 2022-2023. They should also complete their practicals according to the details mentioned in the new Biology syllabus.

Friends, do you find the CBSE Class 11 Biology Syllabus 2022-2023 out of your league? Do your anxiety, tension, and concern for your exam make you restless at night? Do you feel like it's too much to handle this time around? Then don't despair, my friend. There is a new reduced syllabus and fresh notes available only for you on our website. Check them out now as we bring all of your worries to an end.
