@iRabbit these personal experiences and anecdotes are always interesting.
It goes to show that even within top schools, the experiences can vary a lot.
If you are in a top class within a top school, possibly majority will take a H3.
But if you are in an average or below average class within a top school, the profile may be very different.
My kid’s class in JC, it may be surprising to some, about one third took H3s, and not many students are going overseas or pursing Med or Law.
Some parents seem to have the impression that most top school kids end up in Med/Dentistry/Law/CS/Overseas - it may be so for some classes, but I would say it cannot be generalised across all classes in the top schools.
