ICSE Chemistry Class 12 syllabus
ICSE Chemistry Class 12 syllabus

Performance in the class 12th exam is crucial as it can determine the career of a student. ICSE (Indian Certificate of Secondary Education) is a test conducted by the Council of Indian School Certificate Exams. It is one of the most revered boards in India, and the syllabus is quite extensive. In this article, we will understand in detail the various components of the chemistry syllabus, both theory and practicals.

Since preparation for class 12th requires a lot of planning and time management, students should have a clear idea of the portion to study and what to focus on. Students need to understand which concepts are important, the types of questions being asked, and the weightage of different topics.

There are two papers on this subject:

Paper TypeDurationMarks
Paper I: Theory3 hours70 marks
Paper-II: Practical exam3 hours15 marks
Paper-III: Project Work10 marks
Paper IV: Practical File05 marks

Theory Syllabus of Class XII ICSE Chemistry

In this part, there are 16 units comprising different aspects of chemistry – physical, inorganic, and organic chemistry. There will be no overall choice in the paper. Students are required to answer all the questions. The internal option will be available in two questions of 2 marks each, two questions of 3 marks each & all the 3 questions of 5 marks each.
