The 3 x 5500 maint allowance I would call lying.
The 9k which is the Uni fees you will be assured of but you will never see.
Fire back an email asking if the maint is refused what will happen.
And more to the point what the process is and the requirements to qualify for the maint. And do you qualify for it for the full three years before committing to the course.
And what happens if this cash is not available what happens.
I suspect it will be find it or your out and you still have to repay the student loan money later in life what ever you do.
