# Class 9 ICSE Physics Syllabus

Are you curious to know about various advantageous real-life applications of prominent principles of physics like Laws of Motion, Reflection and Refraction of Light, Electrical Circuits, etc.? Then the journey of class 9 ICSE Physics would take you on a tour that aims to impart a thorough knowledge of the core concepts and establish a strong foundation for the crucial class 10th. For students exploring topics to study in class 9th physics along with the ones studying class 9 gauging for syllabus before final exams, here is a blog that aims to highlight critical analysis of the Physics syllabus and exam pattern for class 9 ICSE (Indian Certificate of Secondary Education) board.

## Class 9 ICSE Physics: Exam Pattern

The paper is divided into two parts i.e., Written examination (80 marks) and internal assessment (20 marks). Also, the written paper is divided into sections of 40 marks each. Let us take a look at the detailed inside each section:

• Section I: It is a compulsory question containing short answer questions for all the chapters of the syllabus
• Section II: The section in total offers 6 questions from which students will be expected to solve 4 questions.
