Hi there,
Hope you are doing well.
The 10th class passing certificate is a certificate issued by CBSE to every student stating his final result( only pass or fail) and his list of subjects opted in class 10th.
In some cases of admission to class 11th, it is necessary to submit the passing certificate.
CBSE issues these certificates to the respective schools, from where students can collect it.
Hope it would help.
Thank You
