ICSE Class 10 Chemistry Reduced Syllabus

The syllabus for ICSE Class 10 is believed to be the most challenging among other Board syllabi. Due to the COVID situation prevalent since 2019, ICSE has made several changes in their syllabus and paper pattern. So, it is important to be updated with all such changes for both teachers and students.

Chemistry is one of a few subjects that students really find interesting. Concepts of class 12 are directly asked in competitive examinations like JEE & NEET. It prepares you for career in various domains like Pharmaceutical research, or environmental causes, etc. 

In this page, we have provided direct and free access to the Revised Class 10 Chemistry Syllabus PDF for the Semester-based session 2022-23.
