Here are the points regarding the usage of your West Bengal SC certificate:

1. Validity for State Counseling:

- Your West Bengal SC certificate is valid for state-level counseling and admissions in Odisha, as it is a recognized certificate across states.

- You can use this certificate for state-level counseling and admissions in Odisha without any issues.

2. Validity for All India Quota (AIQ) Counseling:

- For AIQ counseling and admissions, you will need a central-level SC certificate issued by the competent authority.

- The West Bengal SC certificate may not be accepted directly for AIQ, as it is a state-level certificate.

3. Obtaining Central SC Certificate:

- To use your SC status for AIQ counseling, you will need to obtain a central SC certificate from the competent authority.

- This central SC certificate will be valid for both state-level and AIQ counseling and admissions.

- The process to obtain the central SC certificate may involve submitting your state-level certificate and other supporting documents to the designated authority.

In summary:

- Your West Bengal SC certificate is valid for state-level counseling and admissions in Odisha.

- For AIQ counseling, you will need to obtain a central SC certificate, which will then be valid for both state and AIQ admissions.

- The central SC certificate supersedes the state-level certificate for AIQ purposes.

I would recommend you to contact the admissions/counseling authorities in Odisha and the central authorities to understand the exact process and requirements for obtaining the central SC certificate. This will ensure you can use your SC status for both state and AIQ counseling without any issues.
