Hello,

To pursue 12th in Science while keeping your Arts marksheet valid:

1. Contact Education Board : Check with your state or central education board (e.g., CBSE, NIOS) about eligibility and re-enrollment policies.
2. Choose an Open School : Consider open schooling like NIOS , which allows flexibility in changing streams.
3. Apply Fresh Admission : Enroll in 12th Science by submitting required documents (Arts marksheet will remain valid).
4. Subject Selection : Opt for Science subjects (Physics, Chemistry, Math/Biology).
5. Board Guidelines : Follow specific board rules for reappearing in a different stream.

Hope it helps !
