Yeah I think with the changes to HECS it will be at least 92, but no higher than 93 I think.
Law is pretty good if its your thing, I love it but I know some people are totally bored cos its really not their thing.
Arts is ok, I do politics and history and was doing soc up until last week (sociology sucks--DON'T DO IT, FOR THE LOVE OF GOD!)
Arts at Wollongong is a pretty relaxed faculty. Im changing from Arts to Commerce next semester cos I find it hard to do arts subjects knowing that they have zero relevance to my career, but I know some ppl love it for that exact reason.
My advice is to go to the open day, read up on the course and subjects, compare with other unis and then make your decision.
