ICSE Syllabus Updates for Academic Year 2023-2024

The Council for the Indian School Certificate Examination (CISCE) is one of India's main boards of education. It is responsible for conducting the ICSE examination and the ISC examination for classes 10 and 12, respectively. CISCE is known for its challenging, rigorous, and comprehensive syllabus that aims to provide a well-rounded education to students. 

With the advent of the National Education Policy 2020, CISCE has made several changes in its curriculum to include project-based learning to promote critical thinking and problem-solving skills among students. Moreover, it has also introduced new subjects, like Artificial Intelligence (AI), Data Science, and Robotics, in its syllabus.

For the academic year 2023-2024, ICSE has released an updated and revised syllabus that aims to reduce the syllabus by almost 25% for core subjects. The reduction was undertaken considering the problems the normal teaching-learning process faced due to the pandemic.

Overview of the Changes Made by ICSE

Students can understand all of these changes by visiting the official CISCE website and going through the updated syllabus uploaded for 2023, 2024, and 2025 academic years.

  • Annual examinations: ICSE has reintroduced the one annual board examination that will take place at the end of the academic year for classes 10 and 12. It has removed the two-term examination rule that was followed for the academic session 2021-22. 
  • Reduction in the syllabus: ICSE has reduced the syllabus for all core subjects by a major 25% for classes 9 to 12. The syllabus for class 10 has also been revised to include an advanced version of the topics studied in class 9.
  • MCQ section added: The ISC paper has been revised to add a permanent section for MCQs. The number of MCQs has also increased significantly in the exercise questions of every chapter.
  • Types of questions: Questions have been categorised as MCQs, Very Short Answers, Short Answers, and Numericals in the exercise questions, majorly for Physics and Chemistry.
  • Elimination of topics: ICSE has removed various topics from several subjects in classes 9 and 10 to reduce the burden on students.
  • Revised examination pattern: The exam pattern has been revised by ICSE. Students can access the revised pattern on the official website under the regulations and syllabuses section.

Overview of the Chapter/Topic Level Changes Made by ICSE      

In view of the pandemic, ICSE decided to reduce the burden of chapters on students by adopting the revised and reduced syllabus in 2023-2023. However, for this year, 2023-2024, ICSE decided to restore all those chapters and topics which were deleted last year in addition to the introduction of newer topics in the syllabus.
