ICSE Class 11 Physics Syllabus


Students studying in ICSE class 11 should know the entire syllabus of each and every subject before they start preparing for their examination. Knowing the ICSE class 11 physics syllabus will help the students to prepare a exam preparation schedule. This paper is divided in two parts.

Part I – (20 marks): Part I consist of testing knowledge, compulsory short answer questions, application and skills relating to elementary/fundamental aspects of the entire syllabus.

Part II – (50 marks): Part II is divided into three sections:- section A, section B, and section C. Section A will be comprised of 6 questions out of these 6 questions students have to answer any 4 of their own choice, and each question will be of 7 marks. In section B there will be 3 question, each carrying 6 marks, out of these 3 questions students have to answer any 2 of their own choice. There will be 3 questions in section C, each carrying 5 marks, out of these 3 questions students have to answer any 2 of their own choice. Therefore candidates are expected to answer maximum 8 questions in part II.
