hey aspirant

Firstly make sure that all the concepts are clear if not you can refer video lectures available on many platforms and for formulae you can have to revise them regularly or understand the may they are derived , also you have to make notes  and read the chapter line by line form N.C.E.R.T and you will be able to complete the chapter till weekend , and no need to worry you will do well.

All the best

THANK YOU!
