The stage is set for the highly anticipated 2023 National Science and Maths Quiz grand finale, with the top three contenders now settled.

Opoku Ware School, PRESEC Legon, and Achimota School beat some of their fiercest rivals to emerge winners in Thursday’s semi-final match-ups.

Collectively, these three schools boast an impressive tally of 11 championship titles. With such a history, none of these institutions are strangers to the grand finale’s intense battleground. Scheduled for October 31, the finale promises to be a thrilling clash of intellect and knowledge, a true battle of former champions.

It’s a chance for Achimota School and Opoku Ware to seek redemption, as they aim to avenge their losses to PRESEC Legon in the 2009 and 2020 finals, respectively.

Meanwhile, defending champions, PRESEC, have their sights set on an exceptional feat: back-to-back victories. As the current titleholders, they aspire to secure their 8th trophy, to further solidify their position as record holders in the competition’s history.
