3-9 points is what you can get added onto your aggregate through the admissions scheme
http://www.adm.monash.edu.au/admissions/special-admissions-scheme.htmlThat's a link to the Monash SEAS criteria. You might be eligible for more than one, so see which ones you are eligible for and determine how many points will be added onto your aggregate. As a general principle you need about a 170 aggregate for a 94 ATAR, and generally an 89 ATAR requires around and aggregate of 157.
Also, even if you don't get a clearly in ATAR they may take things into account such as any application letter etc.
ALSO - DON'T LOSE HOPE! If high-80s is possible then 90's is possible too! I think it's easy to be dismayed looking at such a difficult goal, but anything can happen at the end of the year. Best of luck.
