This is the 3rd time the Kumasi based school has won the competition.
It was a tight competition as students from the three schools were engaged in a serious mind battle till the end of the final round.
The quiz, which initially involved only 32 schools has over the years, gained a truly national character, involving 135 schools from all parts of Ghana since 2014.
The programme is very popular with Senior High School students, parents especially, with former students (old boys and girls), who take great pride in the performance of their schools on this programme.
