I want to take passing certificate of class 10th .I already mailed info@asknpatna.ac.in what is the procedure?

Usually, they’ll ask for your Class 10 mark sheet, ID proof, and maybe a small certificate issue fee.
Keep both originals and photocopies ready for verification.
If you’re in Patna, it’s best to visit the school office personally for faster processing.
Ask for an acknowledgment slip or receipt after submitting your documents.
The school typically takes 5–10 working days to prepare the certificate.
If you don’t get a reply soon, politely follow up or call the school’s admin office directly.
