Subject Combinations and Additional Subject
CBSE Class 12 students take five main subjects and may take an optional sixth (additional) subject. The rules below are from the CBSE Curriculum 2026-27.
Subject Structure
Subject slot | Rule |

Subject 1 | A language — Hindi or English |
Subjects 2 to 5 | Electives or another language, as per valid combinations |
Subject 6 (optional) | Additional subject — any elective, language or skill subject |

Valid Combinations
Schools must offer subjects according to the Scheme of Studies; invalid combinations are not accepted.
Subjects involving laboratory work need CBSE approval for the school.
Subject changes are not allowed after LOC submission, except in transfer cases.
Key Takeaways
