how can I get the certificate of a language full like intermediate or intro only the name of the language

Answer 1

you can only get certificate for the courses that exist.

Answer 2

no.
there is no C course, only Beginners and Intermediate. You get a certificate for the course, nit the language.

Answer 3

what I mean is that I have completed both the course of c (intro. and intermediate) so will I would be able to get a certificate which says that c is completed.
is it possible?
