I think the only way they could cheat was getting someone else to do it for them.
She's doing maths, as I did, but I can't remember enough to be very helpful, and she wouldn't ask anyway.
Considering some of the lecturers I had, unless it was their speciality I'm not sure how helpful they would be. Judging by one of my tutors they'd probably spend their time recomposing the question to the way they thought it should be.
