You cannot just rely on one book. Chemistry is divided into Inorganic, Physical and Organic chemistry. For inorganic chemistry, you must refer to the NCERT. Coordination points get 9% of weightage. Thermodynamics takes the 8% and Equilibrium takes the 6% weightage slots respectively. Chemical Bonding and Organic structure carries the 5% weightage slot and rest of the topics carry 2-3% weightage in the exam paper.Chemical Bonding, Molecular structure, Solutions, Block Elements, Alcholos, Phenols and Ehters. Aldehydes, Ketones and Carboxylic acids are important topics. Organic comprises of many reactions and reagents which can be practised by writing over and over again. Physical chemistry requires a comparatively deeper understanding of concepts, so preparing with the NCERT and referring to study material a level higher than NCERT should be the way to go.

I cannot guarantee that but I think that you should practice a little more, like you can first solve NCERT and then solve a book like Pandey or something.

You need to have a rigorous practice because the question paper is always highly unpredictable, so not many questions repeat. So practice accordingly.
