CBSE Class 11 Biology Syllabus 2023-24: The Central Board of Secondary Education has made the Biology curriculum open for 11th graders who want to go to a senior high school with a science track. The 11th-grade biology curriculum from the CBSE Board is simple and clear, and the ideas flow from one to the next. Its goal is to show the basic principles that all animals, plants, and microorganisms share and to show how discoveries and new ideas in the field apply to everyday life. Check out and download the Class 11 CBSE Biology course PDF for 2023-24 from the link. This article also contains the list of different chapters with important topics and mark distribution.
