congrats :)
I estimated based on the performance of the 2015 cohort. You can view the number of band6s by school at http://topscores.info/
quantity imported at world price = difference between domestic supply and demand at price of 15 = 40000 units
quantity imported at world price+tariff = difference between domestic supply and demand at price of 20 = 20000 units
difference in quantity imported: 40000-20000=20000
difference in...
I estimated 92.
Not sure of accuracy because of your small cohort.
Have you asked your school for an estimate? I know many top 10 schools provide estimates.
Your marks come from the use of economic theory to justify how globalisation has affected growth/development, and the stats are only towards the end of each paragraph to support your argument. Since HDI is the more conventional measure, I think you can save some words by only using that.
I calculated 68.5. Maths and English weren't kind to your ATAR.
79.5 is your best case scenario according to my calculations
Sorry, I think it's very unlikely you'll meet your first preference. Hope you prove me wrong though.
