In other news, got an email from the admissions dude at Usyd.
Thank you for your message.
Based on the standard required for the Combined Law intake in January 2005, you should be 'very competitive' if you achieve a GPA of 6.0 or better. Of course, the actual standard for 2006 is set at the time the UAC Main Round offers are made. However, history suggests that you should be quite confident of receiving an offer if your results are as you predict.
Please let me know if you have further questions at this stage.
