no it doesnt - it could mean that, ut that's only one of many possible explanations....
It could simply be that a lot of people are like me - got 98.4, but the course i really wanted to do ended up with a 90 cut off as it's not very popular, so for all we know, 99.9% of people in the course had say, 98+ but the last oe in had 90 so the cut off is 90..
I think a lot of peopl forget that the cut off is the LAST person into the course, so i mean, although its unlikely, logically the course could average marks much higher than the cut off would indictae...
other explanations could simply be along with the fact that less people are choosing to go to uni, more people are full fee paying so the hecs cut off's are lower, people with higher marks are no longer just doing law and med coz their schools say they shuold but are researching and doing something they enjoy, people are now more looking to uni's like uws and mac and anu and the like rather than just unsw an dusyd so the cutoffs 'even out' a bit...etc etc etc etc
Most importantly, a lot of people are choosing tafe courses or business college courses or independent IT schools etc etc as they cannot afford university, especially if they don't live within a reasonable distance from o ne and have to move out of home and therefore have to also work etc etc etc
If anything - there aren't more spcaes as a lot of courses are no longer available as they have been dropped due to lack of interest or funds
