Model Answer To Assignment 1
I've put a model answer to assignment 1 on Wattle. You might find it helpful to look at it before you do assignment 2. It was written by an actual student in a previous year. It's not perfect (yours might be better!) but it shows how to get a High Distinction with a very straightforward answer to the assignment task.

It's at http://wattlecourses.anu.edu.au/mod/resource/view.php?id=419545
