ICSE Class 10 Chemistry Syllabus 2023-24

When we talk about science, three main subjects come to our mind, Physics, Chemistry & Biology. We all know their part and importance to our world. Their individuality and interplay with each other is the topic for discussion. Class 9th is one of the crucial grades at which applicants are taken through a little deep exploration of these science subjects. Chemistry is the subject that deals with living as well as non-living because nothing exists without affair & matter is nothing but the aggregation of atoms. The CISCE curriculum for ICSE Class 9 Chemistry is interesting and well-formed to make applicants understand the process, terminologies and experiments of chemistry. This article will explain the CISCE framed a particular syllabus for ICSE Class 9 Chemistry. Before touching on the syllabus it is better to understand its aims & objectives. It will help you to know the subject better.
