It's not discrimination...
By your logic, all university courses should have the same ATAR requirement to get in...
Que? How does that follow...
My point is that if two people have the same ATAR and seek entry into the same course i.e. the JD (not different courses) then there should be no discrimination regarding what they do in their undergraduate course, if there is no undergraduate course prerequisite.
i can totally see where you comming from and how you think it's unfair. Essentailly it comes from this: the commerce faculty take their scolarships exceptionally seriously, (not talking about uni wide scholarships like nationals/access) but the offer a extremely wide range of scholarship-probably more then any other faculty. case in point-they're on an aggressive compaing to raise 5 million dollars for scholarships in the next 5 years, just for commerce students from alumni donations.
The reason that there is a guaranteed place, is NOT because this is something the university had decided, but something that the COMMERCE faculty itself has sought out and negotiated for their top achieving students.
It is not at all a case of a pre-req or anything like that, simply another (albeit rather big) selling point for the commerce faculty.
If you want to to get the same thing for arts students then the scholarship section of the arts department should probably lobby the law department like the commerce faculty presumably has.
The only way this is discrimination is through the fact that the commerce faculty has decided to 'discriminate' and give it's scholarships and use it's influence to help to commerce students as opposed to arts students.
