Difficulty Level of ICSE Class 10 Maths Chapters

In-Depth Analysis: Toughest Chapters in ICSE Class 10 Maths

Let’s break down the chapters that students often find challenging.

1. Trigonometry

Trigonometry stands out as the most feared chapter. With multiple identities to remember, application-based questions, and diagram interpretation, students often feel overwhelmed.

Common Struggle: Misapplication of identities and unit confusion.

Scoring Tip: Practice all variations repeatedly using a question bank for class 10 ICSE to cover standard and tricky formats.

2. Circles

This chapter requires a deep understanding of theorems and properties of tangents and chords. Questions often blend concepts from geometry, making them tricky.

Why It’s Tough: Questions test multiple concepts in one diagram.

Best Approach: Focus on proofs and construction-based questions from the class 10 ICSE math book thoroughly.

3. Heights and Distances

This subtopic of trigonometry involves real-world problems, often requiring imagination and correct figure sketching.

Common Mistake: Misunderstanding angles of elevation and depression.

Solution: Regular diagram-based practice from the best book for class 10 ICSE helps build visual clarity.

4. Factorization

While this chapter seems basic, advanced factorization techniques involving rational expressions and higher-degree polynomials make it tough.

What Makes It Difficult: Identifying the right method – splitting middle term, algebraic identities, or factor theorem.

5. Locus

A conceptual chapter requiring geometric imagination, locus problems are abstract and often skipped, but they do appear in exams.

Which is the hardest chapter in Class 10 ICSE Maths?

Most students and educators agree that Trigonometry is the hardest chapter in ICSE Class 10 Maths. This is due to the need for accurate identity application, understanding angular relationships, and solving real-world problems involving angles and distances. Circles Heights, and Distances follow closely in terms of difficulty due to their conceptual complexity.

Which chapters carry the most weightage in ICSE Class 10 Maths?

Some of the high-weightage chapters include:

• Trigonometry (10–12 marks)

• Mensuration (8–10 marks)

• Geometry: Circles & Constructions (10 marks)

• Statistics and Probability (8–10 marks combined)

Prioritizing these can help you score higher with strategic effort.

Easiest Chapters in ICSE Class 10 Maths

Now let’s look at chapters that students generally find more approachable and easy to score.

1. Probability

With simple concepts and formulas, this is the chapter you should not miss if you're aiming for full marks.

2. GST (Goods and Services Tax)

This is a straightforward commercial arithmetic chapter. Once formulas are understood, questions are predictable.

• Why It’s Easy: Simple percentage and tax calculations.

• Time to Master: 1–2 days of focused practice.

3. Banking

Another arithmetic-based topic with real-life relevance. It involves an understanding of simple interest and recurring deposits.

4. Ratio and Proportion

Simple conceptual questions, often involving direct calculation and little theory.

5. Linear Equations

This foundational topic has simple algebraic manipulation. Most students find it easy if their basics are clear.

Can I score full marks in the easy chapters?

Absolutely. Chapters like Probability, GST, and Banking are consistent in pattern. You can score full marks by practicing from a question bank for class 10 ICSE and ensuring you understand basic formulas.

How should I plan my preparation?

Break your preparation into three parts:

1. Concept Mastery: Use the class 10 ICSE math book to understand all formulas and theorems.

2. Practice: Use sample questions from a reliable question bank for class 10 ICSE.

3. Revision: Revisit easy chapters regularly for speed and confidence.

Time Management Strategy

Based on difficulty and importance, here’s a recommended study time distribution:
