Download ICSE Class 9 Books PDF

These are the 61 chapter-wise books PDFs hosted on icseboard.org for ICSE Class 9, organised by subject. Each section below explains what those books cover before the download table.

Biology

These unit tests cover the Biology branch of Class 9 Science, focusing on the study of living organisms. The chapters include Health Organisations and Waste Generation And Management, which connect biological concepts to real-world public health and environmental issues.

Chemistry

These unit tests cover 21 chapters of Class 9 Chemistry, including symbols, valency, radicals, and the balancing of chemical equations. The material also features additional charts for formulas, valency, and the Modern Periodic Table to help students practice core chemical concepts.

Mathematics

These unit tests span 28 chapters of Class 9 Mathematics, starting with Rational and Irrational Numbers. The chapters cover Compound Interest, Expansions, Factorisation, and Framing of Formulae, providing practice for foundational algebraic and arithmetic skills.

Physics

These unit tests cover 10 chapters of Class 9 Physics, starting with Measurements and Experimentation using Vernier callipers and screw gauges. The material includes Motion in One Dimension, Laws of Motion, fluid pressure, Archimedes' Principle, and Heat and Energy.

What These Science Unit Tests Cover Inside

The Class 9 Science syllabus splits into four branches. Each branch tests different skills, so your revision plan must adapt to the subject.

• Biology covers the study of living organisms, health organisations, and waste management.
• Chemistry focuses on symbols, valency, radicals, and balancing chemical equations by the hit and trial method.
• Mathematics builds on rational and irrational numbers, compound interest, expansions, and factorisation.
• Physics deals with measurements, motion, laws of motion, fluid pressure, and heat energy.

The unit tests in the table map directly to these chapters. They give you a way to test a single topic before moving to the next one.

How to Use These Unit Tests for Exam Preparation

Do not attempt a unit test before reading the chapter. Follow this sequence for each subject to get the most out of these files.

1. Read the textbook chapter first and note the definitions, formulas, and rules.
2. Solve the textbook exercises to build a base before touching the unit test.
3. Attempt the unit test without looking at the book or your notes.
4. Check your answers and mark the questions you got wrong.
5. Re-read the specific topic for every wrong answer before taking the next test.

For Mathematics, keep a separate rough notebook for calculations. For Chemistry, write the valency chart on the first page of your notebook for quick reference. You can find more textbook material on our ICSE books page.

Common Mistakes Students Make While Studying Class 9 Science

Students often lose marks because of small errors that repeat across subjects. Here are the frequent ones and how to fix them.

A common error in Chemistry is leaving an equation unbalanced. The syllabus expects you to balance equations using the hit and trial method. Count the atoms of each element on both sides and adjust the coefficients until they match.

Chapter Highlights Across the Four Branches

Each branch has chapters that carry more weight in unit tests. Focus your effort on these core topics.

• Mathematics: Rational and Irrational Numbers, Compound Interest, Expansions, and Factorisation form the base for higher classes.
• Physics: Measurements and Experimentation, Motion in One Dimension, and Laws of Motion appear in almost every test.
• Chemistry: The Modern Periodic Table, valency, and balancing equations are central to the syllabus.
• Biology: Health Organisations and Waste Generation and Management connect theory to real-world applications.

Frequently Asked Questions

How many unit test PDFs are available on this page?

There are 61 chapter-wise unit test PDFs covering Biology, Chemistry, Mathematics, and Physics for Class 9.

Do these unit tests follow the CISCE syllabus?

Yes, the tests cover chapters from the CISCE-aligned Class 9 Science syllabus, including topics like the Modern Periodic Table, laws of motion, and rational numbers.

Should I take the unit test before or after reading the chapter?

Always read the chapter and solve the textbook exercises first. Take the unit test after to check your understanding of the topic.

Can I use these unit tests for final exam revision?

Yes. These tests work well for final revision because they break the syllabus into chapter-wise sections. You can target weak chapters and test them individually.
