Biology Class 11 Syllabus
Examination is an essential part of the curriculum. Exam questions test your understanding of the concepts. Two exams are conducted in one academic year. Scores of both exams are put together and weighed against the minimum marks required to graduate class 11.
Use NCERT Books to prepare well. The examination is moderately difficult, but the evaluation is strict and thorough. Make sure you solve CBSE Sample Papers and CBSE Previous Year Question Paper to get a better idea of what to expect.An overview of topic-wise distribution of marks helps in planning your studies.
