Is it just me or are half these syllabuses like 10 years old? I checked economics and apparently the syllabus is from 2009, has it really not been updated for that long or am I just looking at the wrong syllabus?
I was once in A2, dropped myself voluntarily to A3 because it's just chiller lowkey. However, we have covered like half of Extension 1 math already up till mathematical induction, so just learn about everything before that.
