CBSE 11 chemistry program with marking scheme (2023)

CBSE class 11 chemical programIt is a big one that needs a clear understanding of concepts and topics. If you know the CBSE chemistry program 11, the students can understand the structure of the chemical course for the academic year.CBSE class 11The students know what to study, the distribution of brands for every unit and the time of time. According to the view, you can plan your study plan without any problems. The final document question is framed for him.

CBSE class 11 practical chemistry 2022-23 with the marking scheme

Practice also plays an important role in chemistry. The students understand the theory by performing experiments in the laboratory. Practical chemistry is 30 brands.

CBSE class 11 practical chemistry 2022-23

CBSE Chemistry Practice are 30 brands. It is carried out under the supervision of the discipline teacher, which contributes to general practical brands for the topic.

The following table shows the practical test evaluation scheme.
