if u got a low average, i dont think so... but with average, you might.
Unless times have changed since then...I got three superiors and a low/below average for reading comprehension and got a first round offer for Mac.rob (more than enough people tried from my school). Whilst someone else from my school who had one superior but no averages (and bands below that scores) only got in through a PD (very deserving though, she ended up being a house captain in year 12). Superiors are prioritised above anything else.
EDIT: Maybe superiors aren't considered above anything else, I have across a few people in Mac.rob that got one low average (maybe below, but probably likely). Also some of those people in those situations, got above averages for all others (got in on PD).
