+1, if you're called for a scholarship interview you know you're going to be offered a place on results day (unless, presumably, you do something truly awful on the day and convince them to change their minds
) but you won't know whether you've got the scholarship until you see the letter - and there are no "full" scholarships: 50% max.
However...good enough for scholarship = more than good enough for an AP. If you applied for an AP, a scholarship interview means you're pretty much certain to be offered the AP (I don't think we've ever come across anyone being rejected for an AP after being interviewed for a scholarship?) and an AP certainly can cover 100% of the fees if income is low enough. So maybe that's what lies behind the story?
