ICSE Class 10 Science Syllabus & Exam Pattern

 The syllabus and testing approach of the ICSE Class 10 Science syllabus and pattern (2026) assess students’ ability to analyze and understand the key concepts of science and incorporate these elements into everyday life. The subject comprises Physics, Chemistry, Biology, and allows students to gain a strong foundation and understanding of the natural and physical world.

At ALLEN, we strongly advocate for conceptual learning and regular practice offered to students through ICSE Science materials, prior year papers, and mock tests, driving students to strengthen their fundamentals which allows them to achieve great success in their 2026 board examination.

1.0ICSE Class 10 Science Syllabus 2026

The ICSE Science syllabus contains 3 types of branches: Physics, Chemistry, and Biology. Each of these branches instils conceptual understanding and practical application of each area of science and builds upon the course of scientific reasoning and observation.

Students need to focus precisely on their theoretical understandings as well as their laboratory experiments, as both will support them in achieving the right score.
