There's a scheme for bonus points, not sure if your careers adviser has told you but there's something called School's Recommendation Scheme (SRS) where your school looks at the students performing very well (after your trials and basically after all the internal assessments are done) then 'recommends' and if your application is successful (or something like that I don't actually know how it works lol), the ATAR is reduced by a lot and you'll make it into courses you were a little bit hesitant in. My Careers Adviser told me that despite the ATAR being at 96-97 for UTS Law, with an ATAR of 80 and your SRS application accepted, you would make it in (which i find very fortunate but a lil skeptical tbh lol). You should ask your careers adviser about possible scholarships (E12, SRS, EAS, etc)
I don't know about transfers but I'm sure you need to get a good WAM (??? i think thats what it is) then you can transfer (altho law, espec at USYD from what I've heard is extremely competitive??) Good Luck Chris!! (if i got your name wrong I'm so sorry)
