I'm doing it now and it's nothing too hard. Just read the textbook and read it over and over until you understand what it's talking about. One tutor told me that the key to passing this unit is to understand the concepts behind the maths- not just the maths itself. Apparently that's important for the final exam.
As with any unit, if you know the textbook back the front your chances of failure are minimal. So just read, read, read, and do all the tute questions and you'll be fine.
I think Rahul has done it, maybe he could shed some more light on the final exam for us?
