Why go Sajc...
So far, I was from there just before they move the the SA
village...
Anyway, it is not difficult to enter using your O lvl grades. Its
not like you need anywhere near 10 A1s.... 
I never knew of anyone appealing in through anything other than
Sports( any kind also can)... They got alot of FTs and ASEAN
scholars so academia not a prob to them.
SA is not intergrated btw.
