NCERT vs Reference Books: Which Is Better for Math?

Every year, as soon as school starts, this one question pops up in every Class 8, 9, or 10 student's mind: "Should I stick to NCERT or dive into those thick reference books like RD Sharma, RS Aggarwal, or Selina?"

It is a genuine confusion. On one hand, your teachers say NCERT is enough. On the other hand, your friends are working through solved RD Sharma copies. Coaching centres push reference books, while toppers often say they stuck to NCERT.

The truth is, both have a role, and the smartest students know exactly when to use each. This guide will break down the strengths and weaknesses of every major math textbook, give you a chapter-by-chapter strategy, and help you build a study plan that works for your board (CBSE or ICSE) and your goals (board exams, competitive exams, or both).

Think of NCERT as the bedrock of your math journey. For CBSE students, it is not just a book; it is practically the blueprint for your board exams. The CBSE question papers are designed directly based on the NCERT syllabus and exercise patterns.

Why NCERT is non-negotiable:

• Every concept, theorem, and type of problem in your board exam is first introduced in NCERT.
  - The explanations are carefully written by expert committees and build concepts step by step.
  - The examples before each exercise are often repeated (with slight changes) in board papers.
  - NCERT is free to download and available in multiple languages.

What NCERT does well:
- Clear conceptual explanations with diagrams.
- Well-graded difficulty within exercises (easy to moderate).
- "Try These" and "Think, Discuss and Write" sections build deeper understanding.
- Sufficient for scoring 85-90% in CBSE board exams.

Where NCERT falls short:
- Limited number of practice problems per topic.
- Does not cover advanced problem types that appear in NTSE, Olympiad, or competitive exams.
- Some chapters have very few exercises (e.g., Class 10 Chapter 9 has only one exercise).
- Does not provide enough variety for building speed and exam-day confidence.

For ICSE students, while the syllabus is broader and requires more depth, NCERT still provides a fantastic conceptual starting point, especially for topics common across boards. It helps you understand the "why" before you tackle the "how" in more complex problems.

If NCERT is the foundation, reference books are your power-ups and advanced training modules. They are packed with a wider variety of problems, different approaches to solving them, and more challenging questions that push your understanding further.

For CBSE Students:

RD Sharma is the undisputed king of CBSE reference books. It offers:
- Exhaustive problem sets (sometimes 50+ problems per exercise).
- Detailed, step-by-step solutions.
- Problems graded from basic to competition-level.
- Excellent for building speed and accuracy.
- Covers HOTS (Higher Order Thinking Skills) questions.

RS Aggarwal is another excellent choice:
- Slightly more concise than RD Sharma.
- Well-organised with clear categorisation of problem types.
- Good for students who find RD Sharma overwhelming.
- Includes MCQ sections that mirror board exam patterns.

For ICSE Students:

Selina Concise Mathematics is the standard reference:
- Written specifically for the ICSE syllabus.
- Concise explanations with ample practice problems.
- Difficulty level matches ICSE board expectations.
- Widely used across ICSE schools in India.

S.Chand Mathematics provides even more depth:
- More challenging problems for advanced preparation.
- Excellent for students aiming for top scores.
- Covers additional topics that occasionally appear in ICSE papers.
- Good for building a strong foundation for Classes 11-12.

Here is the golden rule: NCERT FIRST, Reference Books NEXT!

Phase 1 — Foundation (During school teaching):
1. As your teacher covers a chapter, read the NCERT explanation thoroughly.
2. Solve ALL NCERT examples and exercises — every single problem.
3. Do not skip the "Try These" sections. They often contain important conceptual questions.
4. If you struggle with NCERT problems, do NOT move to reference books yet. Re-read the concept and try again.

Phase 2 — Practice (After completing NCERT):
1. Pick up your reference book and solve additional problems for the same chapter.
2. Focus on problems marked as "HOTS" or "Challenging".
3. If a chapter carries high weightage, solve more problems from the reference book.
4. Use a timer when practising to build exam-day speed.

Phase 3 — Revision (Before exams):
1. Go back to NCERT and re-solve all exercises.
2. Focus on your mistake notebook (problems you got wrong earlier).
3. Solve 2-3 sample papers under timed conditions.
4. Only look at reference books for topics where you still feel weak.

Chapter-wise recommendation for CBSE Class 10:

Let us look at two examples to show how reference books take NCERT concepts further.

The right book depends heavily on your board.

CBSE Students:
- NCERT is your primary textbook. The board exam is designed around it.
- Add RD Sharma or RS Aggarwal for extra practice.
- RD Sharma is better for students aiming for 95+ marks or competitive exams.
- RS Aggarwal is better for students who want structured practice without being overwhelmed.

ICSE Students:
- Selina or S.Chand is your primary reference (NCERT alone is not sufficient for ICSE).
- ICSE math is broader and deeper than CBSE, covering topics like commercial mathematics, set theory, and more complex geometry.
- The ICSE paper is a single $2.5$-hour exam (vs CBSE's $3$ hours), so speed is critical.
- S.Chand is recommended for students aiming for $90+$ in ICSE math.
- Selina is the standard and sufficient for most students.

For students appearing for both boards' competitive exams (NTSE, Olympiad):
- Start with NCERT for concepts.
- Use RD Sharma or previous years' Olympiad papers for advanced practice.
- Focus on problem-solving techniques, not just formula application.

Mistake 1: Starting with reference books before finishing NCERT.
This creates gaps in conceptual understanding. NCERT builds concepts from scratch; reference books assume you already understand the basics.

Mistake 2: Trying to solve every problem in RD Sharma.
RD Sharma has 50-80 problems per exercise. You do not need to solve all of them. Focus on the marked/important ones and HOTS questions. Solve the rest only if you have time.

Mistake 3: Ignoring NCERT examples.
The solved examples in NCERT are frequently adapted for board exams. Many students skip them and jump to exercises — this is a mistake.

Mistake 4: Using reference books as a crutch.
Some students read the solution before attempting the problem. Always try the problem yourself first, struggle with it for 5-10 minutes, and only then look at the solution.

Mistake 5: Not adapting the strategy per chapter.
Some chapters need extensive reference book practice (like Quadratic Equations), while others are well-covered by NCERT alone (like Triangles). Do not apply a one-size-fits-all approach.

Sometimes math can feel like it is just numbers and formulas in a book. But understanding these concepts is building a foundation for your future.

The geometry you learn is used by architects to design buildings. Algebra helps engineers solve complex problems. Trigonometry is essential for navigation, astronomy, and game development. Statistics and probability power the entire field of data science and AI.

Your Class 8-10 math concepts are the building blocks for advanced topics like Calculus, Linear Algebra, and Probability — essential for fields like engineering, computer science, finance, and medicine.

From building India's next big app to designing smart cities, math is the language of innovation. So study hard, because you are learning skills that will serve you for decades.

  - NCERT official website: Free PDF downloads of all textbooks and exemplar problems.
  - Previous years' papers: Available on CBSE's official website. Solving 5-10 years of papers gives you the best exam preparation.
  - Video explanations: For visual learners, video solutions of NCERT exercises can help clarify difficult concepts.

The best strategy combines physical textbooks for structured learning with digital tools for adaptive practice and instant feedback.

• NCERT is non-negotiable: Master it first for conceptual clarity and board exam readiness. It is the blueprint for CBSE papers.
  - Reference books are for depth and practice: Use RD Sharma or RS Aggarwal (CBSE) or Selina/S.Chand (ICSE) for extensive practice and challenging problems.
  - Smart strategy: NCERT first $\rightarrow$ Reference books for extra practice $\rightarrow$ Sample papers for revision.
  - Adapt per chapter: Some chapters need more reference book practice than others. Use the chapter-wise table above as a guide.
  - Consistency is crucial: Daily practice of $1.5$-$2$ hours beats occasional marathon sessions.
  - Maintain a mistake notebook: Track your errors and revisit them weekly.
  - Use digital tools like SparkEd for adaptive practice that complements your textbook study.
  - Connect to real life: Math is not just for exams — it is the foundation of engineering, technology, and innovation.
