hi.
if im not wrong, a pte. dip. frm mdis shld be fine since it's a reputable institution and also if u look under a section (i forgot which section) in the mdis website, you'll realise they have some special rebate only for SIA cabin crew and aircrew alliance members. Which means that i guess SIA recognise this institution since they might have crews going there for further studies too..
im not too sure tho. correct me if im wrong.
