I attended the Friday afternoon session and had the first interview slot, which really was, quite convenient.
I suppose I was a bit disappointed at their lack of enthusiasm during the interview - I thought it was an indicator haha.
It says on the booklet that around 30-35 spots are available for BAcc, so I'd assume they gave the same amount of spots as 'guaranteed' positions. However, as you have mentioned in an earlier post, many will go towards cadetships, gap years etc.
Regarding the ATAR Cut-off, search this forum for threads, keywording "BAcc." I've seen some posts where people have received 91 atar or something.
Furthermore, I think these concerns could be better addressed by the actual program co-ordinators, or current/ex-BAcc students.
