Science · Class 10

A Class 9 or 10 student with no tutor can learn every syllabus topic from this book alone, practise it to board-paper standard, and check every answer in the back.

That means nothing is left for a teacher to fill in. Each chapter starts where you are, builds the idea step by step, and shows worked examples before it sets you a problem. Where a chapter needs something from last year, it teaches that too instead of assuming it. Every printed problem is solved in the back, with hints.

It follows the CBSE Science syllabus for 2026–27 chapter by chapter, in NCERT's order. Each chapter teaches its idea from the beginning, shows worked examples before it sets a problem, and names the mistakes students actually make. Where a chapter needs something from the previous class, the book teaches that too rather than assume the reader has it. Every printed problem is solved in the back, with hints. The back matter carries the solutions, a formula sheet, a mistakes index and a glossary.

What it is not: an NCERT solutions book — it solves its own problems only; a sample-paper or previous-year-paper bank; a coaching module or test series; a CBSE or NCERT publication; the school — no lab work, projects or internal-assessment help.
