For Class 11, 12, and JEE Maths, the best books to use are NCERT textbooks because they cover all the basic concepts clearly and are important for both board exams and JEE. After that, RD Sharma is very helpful for practicing many problems and understanding topics deeply. For JEE-level questions, Cengage Mathematics is excellent as it has challenging problems and detailed explanations. Arihant’s Objective Mathematics is also good for practicing multiple-choice questions, which are common in JEE exams. Starting with NCERT and then moving to these books is a good plan.
