I'm good at Maths, been getting A's and B's on my reports since Year 7. I guess my real question is how much harder is 3U Maths to 2U Maths? Is there not much difficulty between them? Is 3U just more advanced 2U work? I know that Mathematics is just an average scaling subject, so if I'm good at Maths, it will be good to take Extension 1 and take advantage of it's great scaling.
