What are the subject codes of CBSE 10th board examinations?

CBSE doesn't use a single, universally consistent system of subject codes across all years and all schools. The codes used depend on the specific year and the way the school and the board's internal systems are configured. There's no publicly available, centralized list of codes for all subjects for all years.

To find the subject code, you need to:

* Check your Admit Card: The most reliable source is your admit card for the CBSE 10th board exams. The subject codes will be clearly printed there.

* Contact your School: Your school's administration will have the list of subject codes used for the year you took the exam.

Therefore, there is no single answer to your question; the codes vary depending on the specific circumstances.
