Quite difficult. There’s a tremendous density in the pool in the late 460s and early 470s with candidates building up for almost 10 months.. Even with fortnightly draws, points will drop only 1-2 per draw once it gets down to those levels.
Further, there will almost certainly be an FST draw in September or early October, which will delay things again. Last year I was in your same position with 463 and confident I’d get the ITA before my birthday. But then the October FST came and the cutoff score went right back up.
