call them and ask them outright - anything posted here on the forums would only be speculation.. say you want to do law and you've got 97 and ask the kind person on the other line (they won't bite) to tell you if you're likely to get in. remember, not all melbourne kids are interested in moving to a (somewhat perceived) boring city to study undergrad law... they'll prefer to be close to their friends and perhaps spend a few years later on doing postgrad law.
all courses over 98 tend to be those which are specialised to high-fliers... like computational science honours, or bachelor of philosophy, or engineering honours. something as plain and
common as a law degree... i doubt the cutoff will be high. if anything it'll remain constant and anu will just have to cater for more law kids in the lecture theaters or move the law lectures to a bigger theater.
so quit worrying, phone them and hope to get a definite answer and hope for the best
and enjoy your holidays
