Contrary to what people had said about uni being different to VCE after the first two weeks, I like to say otherwise. The content taught in uni may differ from VCE, but without a strong foundation gained from VCE, it makes the subject very hard. You're expected to condense two years of thugs taught (even if its taught slowly, it's quite alot) into two weeks. Obviously there's going to be stuff taught in VCE that wot be covered. There's going to be times where you gape at the lecturer with no idea what he's talking about, while the rest of the VCE people seem to understand it.
This is my experience with physics. Don't listen to people who did VCE chem cause to them, they won't realize how hard is it to get into uni content with a weak foundation. I really suggest you getting a head start and at minimum read through all the VCE chem content and try to familiarize yourself.
