ISC Class 12 Chemistry Syllabus 2026-27 Structure
Updated for the 2027 ISC exams: CISCE has announced changes reported to take effect from 2027 — a pass in English (or the new Modern English) plus at least four other subjects, SUPW/community service as a pass requirement, and Qualified/Not Qualified in place of Pass/Fail. Check CISCE's 2027 regulations and the syllabus for your subject.
Chemistry is a science subject which enables students to study the composition, structure, properties, and changes in matter. The ICSE Class 12 Chemistry syllabus for 2025–26 aims to foster knowledge in physical, organic, and inorganic chemistry. It provides a platform for advanced studies in science, engineering, medicine, and allied sciences. The syllabus integrates theoretical concepts with laboratory exercises for the improvement of analytical skills and scientific thinking and prepares the students well for board exams as well as competitive exams.
Practising past papers is the best way to use this syllabus. Gradehunt’s ISC Class 12 test series gives you chapter-wise and full-syllabus papers with detailed evaluation, so you know where you lose marks before the board exam.
