Okay, a little late on the scene but if you’ve not heard of UNSW Rectangles, you have been deprived of a massive tool that would have made timetabling a lot easier.

To the uninitiated, Rectangles allows you to generate all possible timetables based off subject code inputs for a given semester. You can then view all prospective timetables according to a parameter that suits your lifestyle- be it days off, no early starts, less time at uni etc. etc.

In a nutshell, use this tool.
