Wanna study @ NUS, help~

I will be having SPM this year.
I heard that NUS is one of the top universities in Singapore.
But I have totally no clue about it. Can anyone help?
What are the criterias to fulfill?

@machinistspawned Check out this link - NUS Indicative Grade Profile- which shows the average grades for applicants depending on course. Should give you a good idea.

Btw, NUS is Asia’s No.1 university - see rankings here - QS Rankings 2015
