The Organic Chemistry chapters in the Chemistry question bank are covered most comprehensively. Alcohols, Phenols, Ethers, Aldehydes, Ketones, Carboxylic Acids, Amines - every functional group chapter has 10 years of questions sorted chapter-wise and topic-wise. Competency Based Questions on organic chemistry mechanisms are particularly well-designed. A Chemistry student's dream book!

The Coordination Compounds chapter in the Chemistry question bank is brilliantly covered. IUPAC nomenclature of complexes, isomerism, bonding theories, crystal field theory, applications - all topics have 10 years of ISC questions. Competency Based Questions on coordination chemistry are especially well-designed and challenging. This was my most feared chapter and this book made it my strongest. Excellent!

My ISC Physics and Chemistry teacher officially recommends this Oswaal Set of 5 Books to all Class 12 students. She says the decade of chapter-wise and topic-wise questions with Competency Based Questions is exactly what ISC demands. Her recommendation plus my 22-mark improvement across subjects makes this an undisputed 5-star product. Must buy!

The Ecology and Environment chapters in the Biology question bank are comprehensive and exam-focused. Ecosystems, biodiversity, environmental issues, population ecology - all topics have 10 years of questions arranged chapter-wise and topic-wise. Competency Based Questions on ecology require understanding of real environmental scenarios. ISC increasingly asks such questions and this book prepares students perfectly. Outstanding!

This Oswaal Set of 5 Books is the complete ISC Class 12 board preparation solution. Nothing is missing - Physics, Chemistry, Biology, English Paper 1, English Paper 2 - all five subjects, all chapters, all topics, 10 years of questions (2017-2026), Competency Based Questions, and perfectly organized format. This set is the reason I scored 96.4% in ISC Class 12 boards. Thank you Oswaal!
