The world's top maths achiever is Cape Town's very own.
Dario Trinchero, a 17-year old student at Somerset College, has been placed first in the country for chemistry and first in the world for mathematics in the International Cambridge AS Examinations.
The matric pupil obtained 100% for mathematics after writing the international exams late last year.
Trinchero says he did not expect such stellar results, and does not take all the credit for his success.
I've always been passionate about maths, and have had passionate teachers. All of that is the catalyst for success. I've always done well because I've been surrounded by people that encouraged me.— Dario Trinchero, Somerset College matric learner
He says that he hopes to study both theoretical physics and computer science when he completes high school.
