I think far too many people consider the UAI to be a measure of intelligence, its really not. Yes UWS students may have fewer competitors but how great is that difference really, Uni's are full of mature aged students, full fee students etc... thats assuming also that uai's determine university success which is a lot of crap the best students at UWS are transfer students who got UAI's less than 80! To be fair not all UNSW students got 100, a student like me with a uai of about 94 could have studied at UNSW paying full fee.
Yes the students at UWS may have lower uai's and in some cases leads to a lot less competition but in others it doesn't. Trying to get good marks at an underfunded uni where the expectation is that you are stupid isn't easy trust me amd in my experience marks are awarded on the basis of merit especially in the higher ends, when most people failed the torts assignment less than 5 out of 200 got HD's and < 10% if that got ds.
I think people should just be a little more informed when making comments about the quality of students and challenging if they deserved their marks, I find it a bit rude that the HD in a law subject that I worked hard for is not worth it, because apparently I got it based on the fact that the students at my uni are poorer.
