NCERT e-Solutions adopts a non-conventional yet reader-friendly approach to tackle concepts in Physics for students of Classes XI and XII. The innovative conceptual approach is well supported by explanatory video solutions of the chapter-end questions of NCERT textbooks of Classes XI and XII. The solution videos are uploaded on the physics galaxy web portal for reference. The screenshots of these videos are compiled systematically in this book for quick reference of every solution.The handwritten format of the screenshots gives a clear understanding of the application of concepts studied. It enables quick grasp and revision of the solutions. Once the core concept in solving a question is clear to students, it will be a cake walk to write the solution in the stipulated format expected in the final exams. Every page includes a QR Code, which will take the students to the video solution of that particular question and will help clear any confusion.
