It seems like most people getting into the school would have to move (and thus quit their job).
I'm thinking that maybe they meant working in general (ie, finding another job), but who knows, they aren't very clear (they start off by asking if you worked during vacation from school).
Their residency section also has an error. They way it is worded, you have to do all of the questions if you *are* a resident, but it should be the other way around.
