This is Modern's ABC of Physics for Class XII by Satish K. Gupta, published by Modern Publishers as a two-volume set — Part I and Part II together, Edition 2026-27. It is an English medium (Roman script) book — the complete theory, derivations, solved problems and exercises are in English, and there is no Hindi content in it. The cover states that it is strictly according to the latest syllabus, with digital resources accessible through QR codes. The two volumes together cover the full Class 12 physics course. Part I carries electrostatics, current electricity, moving charges and magnetism, magnetism and matter, electromagnetic induction, alternating current and electromagnetic waves. Part II carries ray optics and optical instruments, wave optics, dual nature of radiation and matter, atoms, nuclei and semiconductor electronics. Both volumes are needed for the complete syllabus. Modern's ABC is a reference book rather than a guide, and its particular strength is the treatment of derivations. Class 12 physics is examined heavily on standard derivations — the expression for the electric field of a dipole, the Nernst-style working in potentiometer problems, the mirror and lens formulae, the Bohr radius — and each is set out here in full with every intermediate step, which is precisely what students find compressed in the NCERT text. Around the theory sit solved examples graded by difficulty, conceptual questions, numerical problems with answers, and objective and assertion-reason questions in the pattern the current CBSE paper uses. For students preparing for NEET and JEE alongside the board, the harder numerical sets here overlap with the entrance requirement, so a single source covers both up to a point. The NCERT textbooks remain what the board sets its questions on; this set is the depth and practice layer above them.
