Agree with factor - 16 hours pw does count as full time, as it does in employment, so presumably she's at college 2 days pw then working the other 3 days?
There will be a student support department at the college - that's where she should be asking these questions, even before she signs up - they will have all the necessary forms she may need to fill in, or they'll tell her where to find them. The course fee is about average in my experience for a full year part time course.
