oooh everyone doing law is going to unsw!
Probably a few reasons for this:
1. A lot of people can make it into law with a much lower ATAR than 99.7 with the AAA scholarship
2. Most people on 99.90 ATAR will go to UNSW because they get scientia there but not outstanding achievement at USyd
3. A lot of people doing commerce/law will head to UNSW because although law is better at USyd, commerce is much better at UNSW. Though obviously a lot of this depends on where you want to go after you finish your degree
4. Just random people like me that like UNSW more than USyd for various reasons
Reason 1 is probs the biggest one
