CBSE Marking Scheme 2022-23

The CBSE board has divided the school year into sessions that cover the whole curriculum so that students can learn the ideas better. The experts use a systematic approach based on how topics and ideas are related to each other. At the end of the school year, the exams will be given by the CBSE board based on the split curriculum. This basically makes it better to have classes run by the board at the end of the year.
