ISC Class 12 Chemistry Paper Pattern
The Chemistry Examination for ISC Class 12 is broken down into two parts:
Theory Paper: Consists of 70 marks and a three-hour time limit.
Chemistry practicals: They are made up of three parts: a practical (15 marks), a project work (10 marks), and a practical file (5 marks).
The Chemistry theory paper is broken into three sections:
The internal choice will be offered in two two-mark questions, two three-mark questions, and all three five-mark questions.
