How and what you grasp from a book depend on you. Arihant publishers are known for good content but you need to prepare systematically because mere buying a book will not help you score 80-90. According to the previous examinations, few topics have been given higher weightage than the rest. Modern Physics take the top slot with 5 questions. Heat and Thermodynamics, Optics, Current Electricity, Elcetrostatics get 3 questions each. Magnetic has 2 questions and the rest get 1 question each. Divide the syllabus into Class 11 and Class 12 and the topics as "Need to Learn", "Weak" and "Strong". Once you complete a topic, try to practise the concepts and write down the important points and paste them somewhere that you can see. Practise questions from that topic. Few more books that can help you are:
