Certificate check

Every certificate carries a server signature. Enter the code from the certificate — the page will show whose it is, for which course and with what score.

The code is printed on the certificate, right under the score.

16 characters. Case, spaces and dashes do not matter, and you need not tell zero from the letter “O”. You can paste the whole link — we will take the code from the end of it.
