For crack her main you should do following things

1.Make basic concept from NCERT books especially in maths and chemistry.

I personally say to you to buy 35 year book bank and solve questions .Take that book bank in which answer is provided to you .This book totally covers all the concept which is asked in examination.

4.You can do mock test which is provided by CBSE during some previous day during her main paper.
