Inter-house General Knowledge Quiz Competition
The Inter-house General Knowledge Quiz aimed to uplift and inspire House Spirits in students in the pandemic. The Quiz was held over two days, the Preliminary Round and the Final Round. After a fierce battler between Buck House and De Sarem House in the Final Round, De Sarem House emerged champions of Inter-House 2021. We believed we raised House Spirits in the four teams that participated and the many spectators who witnessed the Final Round.
