Two primary school pupils from Hong Kong won the top awards in one of Asia's most prestigious maths competitions. It's the first time that any Hong Kong pupil has won a grand champion award at the International Mathematics Contest which was held in Singapore last month. About 1,000 pupils competed in the event which sees teams from the mainland, Hong Kong, Taiwan, Indonesia, South Korea, Malaysia, the Philippines, Singapore and Thailand battling it out in algebra, geometry, statistics and measurements. Nine-year-old boy Li Ka-wing scored the highest marks in the Primary Three category and 11-year-old girl Lam Ho-yan was the best pupil for the Primary Five exams. They both train at the Hong Kong Mathematical Olympiad School in Kowloon which offers intensive maths coaching. 'Each year, there are good results. However this year, it was very special,' the school's principal, Pinky Lam Sui-ping, said. Every year, thousands of Hong Kong pupils applied to compete in the event by sitting online tests, she said. About 200 are invited to sit another selection test before 50 are chosen for intensive training. Finally, about 20 pupils are selected to represent Hong Kong at the event. The principal said Li Ka-wing's level of maths skill was on a par with that of a Primary Six pupil and Lam Ho-yan could easily join a Form Three maths class. 'Li Ka-wing is very smart and clever and Lam Ho-yan is a quiet student who demands a lot of herself.' The Hong Kong team also won seven gold, 11 silver and 14 bronze awards at the event.
