Good understanding of calculus would be helpful to do well in micro-economics, but you can get by without it. Econometrics B (which is not compulsory) requires calculus as well (though it does quickly revise it if you've forgotten the basics about turning points
). Being able to *think* mathematically is probably more important than actual content learnt in HSC for maths with regard to metrics, as everything is explained from scratch. I wouldn't worry too much though, since the tutors will go through it with you if you're having problems and there's a maths learning centre on campus that is especially designed for ppl who did general maths etc who are now doing econometrics.
