Anyone from NUS High School Of Mathematics And Science?

[Future Astronaut]

I'm currently studying in Kuala Lumpur, having done Year 6 in an International School. There are two parts to this question:

1) What are the requirements to be accepted into the school?
2) Do I have to be studying in Singapore to get accepted into the school (I read on the site and it said that the student has to complete primary six in Singapore).

Someone please provide some info.

Thanks.
