Answer 2

These are the best reference books for PCM and english-

• NCERT- NCERT is a necessary book for concept building. It is also important because most questions ranging from 3–5m are given from it. So you need to complete reading and solving questions from NCERT if you want to score good marks.
• NCERT Exemplar- NCERT Exemplar is important because it contains more conceptual questions than NCERT.
• Reference books- Reference books are not needed much but if someone still wants to refer to them, then there are options like  RS Aggarwal for maths  Lakhmir Singh and Manjit Kaur for science (class 10th)  and RD Sharma for maths, pradee[ for physics (class 12th).  
• Question Bank- Question bank is necessary for practising chapter-wise questions of all the subjects. Educart question bank is a good option as they provide numerous questions in a chapter for in-depth knowledge. They also provide important NCERT questions and previous year questions along with new types of questions like case and assertion-based questions.
