Settle down guys.
I think you'll find the OP will be hoping to gain a slot at a school that runs courses eligible for student loan funding.
It's not uncommon for the better schools in New Zealand to interview prospective students with the hope they pick students that will complete the course. The funding (number of student loan slots) they get each year is affected by the completion rate the school has.
There was a time when just about anyone could get onto these courses, those days are gone. Though it might be different in Oz which is where most of the replies to this thread have come from. Seems like there might be plenty of shoddy schools over on the West Island if the Muppet Pastors and other comments are anything to go by.
