Advice

I'm going to start my bachelor of science and I'm doing MTH1010, CHM1011 BIO1011 and ASP1010, just wondering how I can get ready for it? Any notes that people have from doing it that I could look at and overview to get a head start? Any websites or anything else I can take a look at. I'm very bored these long holidays so I just want to see what I'll be getting myself into in March :)
