@Xenophon, after some time on google I found this posted on April 1, 2014:
"A B average and MCATs of 8, 8, 8 taken in one testing sitting since January 2012 is the minimum requirement to be considered for entry."
I remember that was the requirement on the mededpath website as well. They must have changed the website since receiving the news from UQ - although their website currently does not list any time frame at all for the test.
I'm impressed that you are taking the MCAT again! How soon are you taking it and did you inform mededpath?
