interesting seeing you reply, lol.
Anyway, the exact selection process varies from uni to uni. e.g. UNSW looks at your UMAT raw score and your predicted UAI and decide whether they want you for an interview. The final selection depends on you actual UAI, UMAT and your interview performance (equally weighed)
But UNCLE looks only at your UMAT when they issue an interview invitation, the final selection depends on mainly on your interview performance, but also a little on your UMAT. if you are a standard applicant as long as you get an UAI of 93.8+, they wont worry about your UAI.
