If you have a compartment in Mathematics in CBSE Class 12 and want to apply as a private candidate, here's what you need to know:

1. Applying in Multiple Subjects: As a private candidate, you can generally appear for multiple subjects.

You can choose to appear in subjects like Chemistry or Physical Education along with Mathematics, but ensure that you check the specific guidelines from the CBSE for private candidates.

2. Filling College Admission Forms:

- Status: Indicate your current status based on your situation. If you are still appearing for the compartment exams, you might need to state that you are appearing for exams in 2025.

- Clarify Compartment Status: If the form asks about your examination status, you should mention that you have a compartment in Mathematics and are addressing it as a private candidate.

3. Future Exams: Make sure you meet the college's admission requirements and deadlines.

Some colleges may require proof of passing all subjects before admission.

4. Consult College: Contact the colleges you're interested in to clarify how your compartment status might affect your application.

For accurate information, always refer to the latest CBSE guidelines and contact the admissions offices of the colleges you are applying to.
