How can you people say this school is better than the other etc. by looking at the A/L results of only ONE person from a school? I doubt his/her school did a lot in helping him reach that goal. Otherwise, why wouldn't there be like 15-20% people getting selected for Engineering, Medicine etc. from that school? It all comes down to the commitment a certain individual puts at it.
P.S.
At least Royal College has a very high rate of how many people enters a university per exam participant. In 2003, around 80 people entered University of Moratuwa, out of around 300-350 people. (In Maths)
