As they mentioned, minimum requirement is 5 or 6 O levels passes in 1 sitting which includes Eng, Maths etc etc... Yeah?
But then, just by meeting the minimum requirement does not guarantee entry and acceptance...
But of cos, SIA has quite a number of degree holders to choose from... not to mention pple with relevant experience, flying history, Masters... Honours... etc etc...
Looks like a simple Degree might not even cut it anymore...
But i do know of Diploma holders who are with SIA... So all is not lost...
I'm not too sure abt Malaysians though... Sorry.
Good Luck!
