Faith Odunsi, a Nigerian student, won a global math competition, beating China, the United Kingdom, the United States, and others — a move that cemented her place in history.

Odunsi, the winner of the Global Open Mathematics competition, excelled in all rounds of the competition and didn’t think she’d be declared the winner until the final round when she answered more questions than her rivals.

In an interview with The Punch, Faith said, “My heart raced but I felt relieved.” Odunsi is currently in her senior year of high school at the Ambassadors School in Ota, Ogun State. Odunsi’s father is a doctor, and her mother is a businesswoman, and she credits her father for her mathematical proclivity.

Odunsi describes her feelings about this achievement as “happy and honoured.” Despite the stiff competition, Odunsi came out on top by a 30-point margin. She now has not only the title, but also a $1,000 reward as the competition’s winner.
