This is the official NCERT science book class 10 (2026-27 edition), covering all 13 chapters of the current CBSE syllabus — the board-exam-year science book, covering chemistry, biology and physics in one volume. This ncert class 10 science book pdf covers every chapter below.
What’s in the Class 10 Science NCERT Book (2026-27 Edition)
Chemical Reactions and Equations, Acids Bases and Salts, Metals and Non-Metals and Carbon and Its Compounds form the chemistry section; Life Processes, Control and Coordination and Heredity and Evolution form biology; Light, Electricity and Magnetic Effects of Electric Current close the book with physics.
Study Tip
Numerical problems from Electricity and diagram-based questions from Light are two of the most consistently repeated board question types — prioritise these two chapters if time is short.

Why This Book Matters for Boards
Because this single book covers three subjects, CBSE Class 10 Science papers draw roughly proportional questions from Chemistry, Biology, and Physics sections, so no area can be safely skipped. Biology chapters like Life Processes and Control and Coordination reward careful diagram labeling and precise terminology, alongside the numerical strength needed for Chemistry and Physics. Balancing revision time evenly across all three subject areas, rather than favouring a stronger one, is the most reliable way to maximise overall Science board marks.
Frequently Asked Questions
Is this the current 2026-27 NCERT edition?
Yes — every chapter linked above is pulled directly from the official NCERT source at ncert.nic.in, so it always reflects whatever NCERT currently has published for Class 10 Science for the 2026-27 academic session.
Why does this book matter for board exams?
Class 10 is a CBSE board exam year, so this book’s chapters form the direct basis for the board syllabus. Downloading the official version (rather than a summarized or third-party copy) ensures you’re studying from the exact source the exam is set against.
How many chapters are in the Class 10 Science NCERT book?
There are 13 numbered chapters (plus front matter) covering Chemistry, Biology, and Physics together in a single combined book.
Is the book available in Hindi medium?
Yes, NCERT publishes a Hindi-medium edition of this book (Vigyan) on its official textbooks portal alongside the English edition.
How is this book split between subjects?
Roughly the first five chapters focus on Chemistry, the next three on Biology, and the final four on Physics, though CBSE exams draw questions proportionally from all three.
What is the difference between the NCERT textbook and the NCERT Exemplar for Class 10 Science?
The textbook covers core concepts and standard exercises, while the NCERT Exemplar offers more challenging problems for additional practice once the textbook is mastered.
What is the best way to study from this book?
Read each chapter for concept clarity, practice numerical problems in Physics and Chemistry chapters, memorise key diagrams and definitions, and revise all three subject areas evenly rather than favouring one.
