A Sekondi district magistrate's court on Tuesday imposed a fined of 200 Ghana cedis each on two brothers, Celestine Hackman and Gaddiel Hackman for impersonation.
In default the convicts, who pleaded guilty would serve nine months in jail in hard labour.
Police Chief Inspector Joe Hedidor said Celestine asked his younger brother Gaddiel to write the West Africa Senior Secondary Certificate Examination for him to improve upon his grades.
Chief Inspector Hedidor said both were given index numbers and Celestine was given Bompeh Secondary Technical School in Takoradi, as the examination centre while Gaddiel was to write the examination at Ahantaman Secondary School at Ketan.
He said on October 13 this year, the convicts wrote the Physics paper at their respective examination centres but when the scripts were being collected after the examination, it was detected that Gaddiel wrote the paper with Celestine's index number.
Chief Inspector Hedidor said the matter was reported to the Western Regional Controller of the West Africa Examination Council who ordered the arrest of the brothers.
