Hello,

The best book is NCERT. You will understand the basic concepts from there. For more number of numericals you can use NCERT on yourfingertips by MTG , OP tondon book. Arihant is also good.

You can use this book to solve problems,understand concepts, to know why the problem is solved in that way and why not in the another way. why that particular formula is used. What scenario is associated with which formula. keep getting answers for these set of questions every time you study or practice questions.

NCERT is one stop source and solve as many questions you can. Solve previous year papers too to know how the questions were asked in the exam. you can appear mock tests too to know how you perform and your weak part.

Hope it helps!
