That is the same with me, I am more confident in the interview than the ATAR and UMAT hurdle.
No, I haven't taken any UMAT or Interview classes. I joined Medstudentonline; that said, I do tend to fuss over these kind of things. My classmates come to me for Uni advise on anything instead of the careers advisor. If you are interested in UMAT seminars, you can ask here in the Med section. If you go on Medstudentsonline, they have various questions composed by the members that are like the questions. However, it does not allow UMAT seminar discussion.
No problems with the questions- like I said, I am happy to help :)
Also, here is a link to the mock questions in UMAT ( go to 2nd post)
