Jk44,
if you were unsuccessful at the P+S then that means you missed the cutoff score.
Yes, they will reconsider you in the timeframe given, but I strongly recommend you get in and do some preparation before the day.
Take a look on the QF website as the test for them and Eastern is the same. You will find examples of some of the content you might expect on that site. If you've done it the first time, then you know what to expect.
I'd have a crack at some of the IQ books put out by the Mensa Foundation as a starting point. You can find those in newsagents Australia wide.
Exercise your brain. You'd be surprised what a difference it makes on the day.
