Wow they've made a guarantee ATAR for entry... It means that if you complete an Australian Year 12, or the IB in Australia, in 2012 and achieve an ATAR or equivalent of 95.00 then you will be guaranteed a position in B.Comm in 2013.
The clearly in is the cut off, so the lowest ATAR you can get to get an offer for the course. If you're below the clearly in and don't have SEAS then you can pretty much say good bye to entry into that course. IIRC the clearly in for 2010 for B.Comm was 94.15~ give or take 0.3 and it was 95.45 last year.
I don't see how they can have a guaranteed entrance scheme, in the extreme case where say all students who achieve 95.00+ apply for B.Comm do they only accept the maximum number of students they're allowed to or would they have to accept all since it's 'guaranteed'.
