I just want to respond to Linda Miley's letter.I think she just look at one side of the coin.There are many things that contribute to the failure of students.By just pointing on particular things is not the point.There are students who still does not do the things you describe but yet failed their units and there are students that match what you have stated but still pass their units. The point i want to stress is this, at University level it is the matter of doing your work that matters.
