Hello Aaisha,

In Chemistry question paper, you will hardly find any numerical. The only chapter containing numerical is surface chemistry. So there are chances that you will find one numerical from the chapter.

There is no such exact weightage but in class 12 the physical chemistry is of 23 marks excluding surface chemistry as there is no numerical in it but considered in physical chemistry then the weightage is 18 marks nearly 12–15 marks for numerical.

Though this is a very rough prediction.

Prepare everything well. Good luck!
