Poly is big fuck meh? I know people who got into a US uni with their O level results and a good SAT score.
At the U I was studying there was a 16 year old from Spore who did just that. He was really smart & would get A's for almost all the courses he took.
Before he had to return to Spore to do his NS, he had already completed a double degree because he took extra credit during the summers.
He was scholastically brilliant. Also an accomplished musician
The reason I remember him was because not only was he a smart guy but also a nice guy
That is pretty rare
I heard that he applied to Harvard but was rejected because he was too young.
