The West African Examination Board (WAEC) warned candidates in the West African High School Examination (WASSCE) against scammers who are prone to jeopardize the exam.
Mr. Demianus Ojijeogu, head of the public relations department, WAEC, issued a warning in a statement in Abuja on Thursday.
He said that the attention of the council was drawn to the recent activities of these scammers.
Ojijeogu said that past issues were published through some social networking platforms by scammers who claim that "these are documents that must be written by candidates."
"WAEC's attention was drawn to the activities of scammers who could jeopardize the performance of trusting candidates in the current WASSCE for private candidates, the 2018-Second Series in Nigeria.
"The Council was dismayed to observe that past issues are published through WhatsApp and criminal websites by scammers, which they claim are documents that have not yet been written.
"For example, the questionnaire on the principles of cost accounting, which was written in Sierra Leone and the Gambia on Thursday (today), is distributed by these criminally-minded elements.
"The document is distributed among candidates in Nigeria as" Financial Accounting ", scheduled for tomorrow (Friday).
"The success of our candidates is our main concern, and the council wants to advise all candidates not to become a victim of these scammers, but to concentrate on learning."
