Biology Class 12 Notes: Revision notes are the short textual content from the textbooks that summarises the chapter in fewer words. This helps students have a quick review of what they have learned in their class. Completely relying on revision notes won't be a great choice, as you must have an idea about the chapter and concept mentioned under the short notes. These are merely for revision purposes, not for cracking or scoring 100% in the exams. But yes, if students know the chapter well and refer to revision notes, they will definitely get a higher score.
In this master article, you will find the important and short revision notes for your CBSE Class 12 Biology. These CBSE notes are designed based on the revised syllabus and NCERT Class 12 Biology revised textbook. Check and download the revision notes here.
