A 12-year-old maths whiz who is studying at university is trying to help other students learn.
Tristan Pang, who attained 91 per cent in the Cambridge A Level exam, is head boy at Ficino School in Mt Eden, and is also taking maths papers at the University of Auckland.
Next year, he will study maths and science full-time at the university, with the aim of becoming an inventor or scientist.
Tristan has previously featured in the Herald after winning an award for a science project that put claims behind Fonterra's light-proof milk bottles to the test.
His advanced studies are all done in his own time, and now he has added to the after-school workload by setting up a website to teach others.
