Most NCERT solution platforms start free and gradually move content behind a subscription. Tiwari Academy operates differently – the platform is funded through non-intrusive advertising, which means the solutions themselves are never monetised directly and never will be. A student from a rural school with a basic Android phone and a slow connection gets the same access as a student in a metro city with a premium subscription elsewhere.

NCERT has introduced new textbooks under the National Education Policy (NEP 2020) Framework and Tiwari Academy now provides complete, chapter-by-chapter solutions for every newly introduced book.

• Kaveri – English for Class 9
• Ganga – Hindi for Class 9
• Exploration – Science for class 9
• Understanding Society – India and Beyond – Social Science for Class 9
• Ganita Prakash — Mathematics for Classes 6, 7 and 8
• Curiosity — Science for Classes 6, 7 and 8
• Poorvi — English for Classes 6, 7 and 8
• Malhar — Hindi for Classes 6, 7 and 8
• Deepakam — Sanskrit for Class 6, 7 and 8
• Sarangi — Hindi for Classes 1 to 5

These solutions are prepared specifically for the revised chapters, new exercise formats and activity-based questions in the updated books — not adapted from older editions. If your school has moved to these new textbooks, you are in the right place.

Chapter-by-chapter solutions covering all subjects – Maths, Science, English, Hindi, Social Science, Sanskrit, Physics, Chemistry, Biology and Economics – in both Hindi Medium and English Medium, updated for the 2026-27 session including new NEP textbooks.

NCERT Solutions are chapter-by-chapter answer guides for the textbooks prescribed by NCERT and followed by CBSE schools across India. Each solution explains the method, formula or reasoning behind an answer – not just the final result.

At Tiwari Academy, these solutions are prepared by qualified subject teachers, reviewed for accuracy and updated at the start of every academic session to reflect any syllabus revisions. They are used by students for homework, daily self-study, exam revision and doubt-clearing; by teachers as a reference while preparing lessons; and by parents supporting their children at home.

For competitive exam aspirants, NCERT content forms the foundation for JEE, NEET and UPSC preparation – making a thorough understanding of these solutions essential, not optional.

Who uses them:

• Students (Class 1-12) — Homework help, self-study, exam preparation and concept clarity.
• Teachers — Reference material for lesson planning and question-paper preparation.
• Parents — Helping children understand difficult homework problems.
• Coaching centres — As a teaching aid and baseline reference alongside advanced material.

Quality and Reliability of Solutions
NCERT Solutions are generally prepared by experienced educators, subject experts and educational organizations. The quality can vary depending on the source, but solutions from reputable publishers and educational platforms are typically reviewed for accuracy and pedagogical effectiveness.
Authentic and Reliable Solution:
Tiwari Academy provides simple, reliable answers from expert teachers. We quickly respond to questions from students and teachers, making learning easy and understandable.

For students in Classes 9 and 10, NCERT textbooks are the primary source for CBSE board exam questions. Understanding the logic behind each answer — not just memorising it – is what separates a 70 from a 90 on a board paper. Tiwari Academy’s solutions for Classes 9 and 10 explain every step, include diagrams where the textbook requires them, and follow exactly the answer format that CBSE examiners expect.
Subjects covered: Mathematics, Science, Social Science, English, Hindi (Course A and B), Sanskrit. Solutions are available in both Hindi Medium and English Medium.

• Class 9
• Class 10

Class 11 and 12 are the two most consequential years in school — board results, college admissions and competitive exam eligibility all hinge on them. Tiwari Academy provides complete, step-by-step solutions for every exercise and example in the Class 11 and 12 NCERT textbooks across all streams.

• Science stream: Mathematics, Physics, Chemistry, Biology
• Commerce stream: Accountancy, Business Studies, Economics, Mathematics
• Humanities stream: History, Geography, Political Science, Sociology, Psychology
• Common: English, Physical Education

Solutions include numerical derivations, proof-based questions and long-answer formats written in the style expected by CBSE board examiners.

• Class 11
• Class 12

CBSE board exams for Class 10 and Class 12 are based almost entirely on NCERT textbooks. Every solution on Tiwari Academy for these two classes is written in the exact answer format that CBSE examiners follow – including the number of steps, the diagram requirements and the mark allocation per step. Knowing the right answer is not enough; knowing how to present it for full marks is what separates a 75 from a 95.

1. Direct source of questions — Over 85% of CBSE board exam questions in Class 10 and Class 12 are either directly from NCERT exercises or closely based on them. A student who has thoroughly worked through every NCERT solution has already covered the majority of what the paper will test.
2. Marking scheme alignment — CBSE releases a detailed marking scheme for board papers. Tiwari Academy’s solutions follow this scheme: each step carries the marks it would receive in an actual board answer sheet, so students learn to write answers that examiners can award full credit to.
3. Diagram and derivation format — For subjects like Physics, Chemistry and Biology, diagrams are mandatory in board papers. Our solutions include labelled diagrams wherever NCERT or CBSE expects them, drawn to the standard expected in a board exam context.
4. Long-answer structure — Class 12 board papers include 5-mark and 6-mark questions that require structured, multi-point answers. The solutions here follow the introduction–explanation–conclusion format that CBSE examiners look for.

• First attempt, then compare — Never read the solution before attempting the question yourself. Write your answer, then open the solution and compare step by step. This builds the muscle memory that works under exam conditions.
• Mark your weak steps — If your method matches but one step differs, mark that step and revisit it three days before your exam. Small step errors are where board marks are most commonly lost.
• Practise answer length — Board examiners are trained to give full marks only when the answer is of the expected length. Use our solutions as a benchmark for how many lines a 3-mark answer requires versus a 5-mark answer.
• Pair with sample papers — After completing chapter-wise solutions, move to Tiwari Academy’s CBSE Sample Papers for Class 10 and Class 12 to practise in the actual exam format with time limits.

For India’s most competitive entrance exams, NCERT is not just a starting point – it is the syllabus backbone that every other resource builds on. Whether you are targeting JEE Main, JEE Advanced, NEET or UPSC Civil Services, a strong command over NCERT content is mandatory – and that is exactly where NCERT Solutions help.

For JEE & Engineering Entrance Exams:

• Class 11 and 12 Maths, Physics and Chemistry solutions are the core foundation for JEE Main.
• Step-by-step derivations, formulas and numerical solutions help build problem-solving speed.

For NEET & Medical Entrance Exams:

• Class 11 and 12 Biology and Chemistry solutions are essential for NEET aspirants.
• Diagrams, definitions and assertion-reason answers are included in the solutions.

For UPSC & Government Exams:

• NCERT books for Class 6 to 12 in History, Geography, Economics and Political Science are recommended reading for UPSC aspirants.
• Our solutions help you understand and retain the content of these books efficiently.

NCERT Solutions in Hindi Medium are available on Tiwari Academy for all classes from 1 to 12, across all major subjects. These are not translations of English solutions – they are written originally in Hindi, in the language and style that matches what a Hindi-medium board examiner expects in an answer sheet.

Most state boards across northern and central India either follow NCERT textbooks directly or follow a curriculum that closely mirrors them. If your state is listed below, the solutions on this page apply directly to your board exam preparation.

• Class 10: Ganit (Mathematics), Vigyan (Science), Samajik Vigyan (Social Science), Hindi, Sanskrit
• Class 12: Ganit, Bhautiki (Physics), Rasayan Vigyan (Chemistry), Jeev Vigyan (Biology), Lekhashastra (Accountancy), Vyavsay Adhyayan (Business Studies), Arthashastra (Economics)
• Class 9: Ganit, Vigyan, Samajik Vigyan, Hindi, Sanskrit
• Class 6, 7, 8: Ganita Prakash (Maths), Curiosity (Science), Malhar (Hindi), Deepakam (Sanskrit), Samajik Vigyan
• Class 1–5: Sarangi (Hindi), Ganit, Hindi Vyakaran

1. Answer language must match — A UP Board or Bihar Board student writing their answer in Hindi must use subject-specific Hindi terminology — VIDHYUT DHARA not current, SAMIKARAN not equation. Solutions written originally in Hindi use this terminology naturally, while translated solutions often get the terms wrong or use a mix of languages that costs marks.
2. Answer format is different — Hindi-medium board papers expect a different sentence structure and answer length compared to CBSE English-medium papers. Our Hindi solutions are written to match this format specifically.
3. Vyakaran (Grammar) coverage — Hindi Vyakaran solutions are available separately for Classes 1 to 8, covering Sangya, Sarvanaam, Kriya, Visheshan, Sandhi, Samas and all other grammar topics in the NCERT curriculum.

• NCERT Solutions for Class 10 Hindi

UP Board switched to NCERT textbooks from the 2019 session. Since then, UP Board Class 10 and Class 12 papers have drawn questions directly from NCERT exercises. A UP Board student using Tiwari Academy’s Hindi Medium solutions is studying from the same source that their board paper is built on – which is the most efficient exam preparation strategy possible.

NCERT solutions are not exclusive to CBSE. Students across UP Board, Bihar Board, MP Board, Rajasthan Board, Uttarakhand Board, Jharkhand Board and several other state boards follow a curriculum based on or closely aligned with NCERT textbooks. If your state board uses NCERT books, these solutions apply directly to your exam preparation.

For UP Board and Bihar Board students in particular, Tiwari Academy’s Hindi Medium solutions are especially useful – answers are written in clear, exam-appropriate Hindi rather than translated from English, making them easier to understand and reproduce in your own board examinations.

Subjects covered for state board students:

• Mathematics (all classes)
• Science – Physics, Chemistry, Biology (Classes 6-12)
• Social Science – History, Geography, Civics, Economics
• Hindi Vyakaran and English Grammar

Key Advantages of Tiwari Academy Solutions
Most NCERT solution platforms either hide content behind a login, charge for PDF downloads or show intrusive ads during study sessions. Tiwari Academy was built on a different principle: every solution, for every class, for every subject, stays free – permanently.

• Competitive Exam Preparation: For students preparing for competitive examinations like:
  • JEE (Joint Entrance Examination) for engineering
  • NEET (National Eligibility cum Entrance Test) for medical
  • UPSC (Union Public Service Commission) for civil services
  • Other state and national level competitive exams
  NCERT books provide the foundational knowledge and their solutions help in thorough concept understanding.
• Concept Clarity and Understanding: The detailed explanations help students grasp fundamental concepts rather than just memorizing answers. This builds a strong conceptual foundation.
• Self-Study Tool: Students can independently verify their work, understand where they went wrong and learn the correct approach without always needing a teacher’s assistance.
• Homework and Assignment: Students use these solutions to complete their daily homework solutions and understand difficult problems like exemplar or private publisher books.
• Time Management: Having readily available solutions helps students save time during revision and school test and board exam preparation.

• Official Sources: The NCERT website provides free access to textbooks and some supplementary materials.
• Published Books: Numerous educational publishers produce NCERT solution books that are sold commercially in bookstores.
• Digital Platforms: Many educational websites like Tiwari Academy, mobile applications and online learning platforms offer free and paid NCERT solutions with additional features like video explanations.
• PDF Format: Downloadable PDF versions are widely available online for offline access.

1. Comprehensive Coverage: Every question from every chapter of NCERT textbooks is answered, including in-text questions, exercise problems and additional questions.
2. Step-by-Step Explanations: Solutions don’t just provide answers but explain the methodology, formulas, concepts and reasoning behind each solution, making it easier for students to understand the problem-solving process.
3. Subject-Wise Organization: Solutions are available for all major subjects including:
   • Mathematics
   • Science (Physics, Chemistry, Biology)
   • Social Science (History, Geography, Political Science, Economics)
   • English
   • Hindi
   • Sanskrit
   • Other regional languages
4. Class-Wise Arrangement: Organized for Class 1 to 12, from elementary classes through higher secondary education.

1. Complete concept understanding: Solutions explain the method behind every answer, not just the final result, which builds understanding rather than rote memorisation.
2. Self-verification: Students can attempt a question on their own, then compare their approach with the expert solution to identify exactly where they went wrong.
3. Board exam alignment: Most CBSE board questions are drawn directly from NCERT exercises; knowing these solutions means knowing what examiners expect.
4. Competitive exam foundation: Class 11 and 12 NCERT content forms the core syllabus for JEE Main, NEET and UPSC; these solutions build the necessary base.
5. State board applicability: Students on UP Board, Bihar Board, MP Board and other NCERT-aligned state boards can use these solutions directly for their own exams.
6. Hindi Medium support: Answers in Hindi for students who study in Hindi-medium schools, written to match the language expected in Hindi-medium board papers.
7. Bridging missed classes: When a student misses a topic, a clear step-by-step solution with explanation acts as a substitute for a classroom session.
8. Structured revision: Chapter-wise organisation makes it easy to revise a complete topic quickly before an exam without re-reading the entire textbook.

The most effective way to use any solution guide is to attempt the question yourself first, then compare your approach — not copy the answer. Read through the step-by-step explanation to understand where your method diverged, make a short note of it and try the question again a few days later during revision. That cycle — attempt, compare, note, revisit — is what turns a solution guide into a learning tool rather than a shortcut.

For board exam subjects (Classes 10 and 12), pair these solutions with Tiwari Academy’s chapter-wise MCQ tests and CBSE sample papers to practise in the format that examiners actually use. The solution explains the concept; the MCQ and sample paper test whether you have understood it well enough to apply it under exam conditions.

For competitive exam preparation — JEE, NEET, UPSC — treat NCERT solutions as the foundation layer. Master the NCERT content first, then move to advanced reference books. Students who skip NCERT and go straight to advanced material consistently find gaps in their understanding during mock tests and revision.

If you find a step unclear or believe a solution needs correction, post your question in the discussion forum — every question receives a response from the Tiwari Academy team.
