So you're saying WAEC has the right to issue a certificate for an exam not conducted by them?

StOla:
Channels or Chris Nwaokobia who gave his own ignorant opinion is not Cambridge.

Cambridge has since replied to this lie since 2015. And till this very day, the same information is still available on the official website of Cambridge Assessment given in the link below.

Besides the Cambridge result master sheet shows that Hausa was offered, and many besides Buhari wrote the paper.

Maybe your ignorant Channels source is telling us they all wrote an imaginary exam, or Cambridge is unaware of its own exam records?

What is evident is that many are ignorant and those who peddle this propaganda are unrelenting, and are determined to exploit the mental handicap of the educated illiterates of Nigeria.

Also attached below is a sample of 1961 WASC certificate (not for Buhari) from Cambridge and WAEC, guess what, it has no certificate number.
It only has an Index No. Which is the center number/Candidate number.
On the certificate is written clearly that this index number is 8390/152, while for Buhari we know it is 8280/002 for the center No (8280) and the candidate No (002).

So WAEC is right to have issued an attestation with a registration number but Original Certificate Number is N/A for 1961.
