Hi

Eligibility for first graduate certificate is

1. Candidate should be a residence of Tamil nadu.

2. No other person in the family should be a graduate

3. No siblings should have got or registered for th at certificate meaning they should not have availed its benefits.

If you fit into this category you can apply for it as though your brother is a graduate he has not availed any of its benefits.

let me know if you have any other query.
