When I first saw my results I thought I was doomed. I was extremely disappointed with my results and I'm also repeating 3U (because I know I can achieve around the lower-mid 90s) and I've done about 75 past papers and that is no joke... went through 600+ pages of paper and 7 pens.
But, yes, I did get in and I'm very glad I did... I love the course. Also, the course application requires a principal's recommendation in which I believe mine spoke extremely high of me + a breakdown of preliminary results (which I achieved dux of Year 11 with numerous 1sts) so I believe the preliminary track record was quite significant in my application along with the actual results.
I don't suppose you applied?
