I am really worried because most my subjects don't scale well and if I don't get 90+, it is going to drag my atar down significantly? I popped all marks below 90 in an ATAR calculator and I got an atar of like 60 Does this mean I need to replace with some high scaling subjects? I really like the subjects I picked, but I don't want to take the risk of getting scaled down if i don't get 90+. Someone told me you should be doing at least 2 sciences, and at least Extension 1 Mathematics if you want to get an high atar.
