One hundred teams battled it out at Jubilee Stadium, putting their brains to the test in Whanganui High School's first house quiz.
About 500 students from Awa, Maunga, Moana and Whenua houses combined to take on each other, answering 10 questions from 10 categories with prizes on the line.
The grand prize was a trophy designed by head of technology Craig Adam which incorporates the house names and the meanings behind them.
Whanganui High School prefects Raoul Sarup and Rhea Colaabavala helped to organise last Friday's event.
"The house system's new this year, this was a way that we could incorporate an academic event and get people involved in something that isn't sports," Sarup said.
