If I did my hsc maths in 2010, and keep my score, will my mark for the calculation of my atar be compared to 2010's cohort or 2011's cohort (this year). Im not sure if this makes sense :S
ur maths agregrate score should be based on 2010 i.e. the scaling for maths will be based on 2010 and then that marks will be added to ur agregrate for 2011 atar calculations
