SyllabusCBSE class 12 syllabus 2026-27: subjects and marks
Class 12 is the Senior School Certificate Examination. Subjects differ in how the 100 marks are made up. Subjects with laboratory work, such as Physics, Chemistry and Biology, have a theory paper of 70 marks and a practical examination of 30. Mathematics and English Core have a paper of 80 marks with 20 of internal assessment. Accountancy, Business Studies and Economics have a paper of 80 marks with a project of 20.
