Anything is possible, their isn't really a "limit - except scaling wise" and is now based upon the HSC exams. The only subject you have with decent scaling is advanced english, and the others not really good. I don't know much about these subjects, except I got some general knowledge of what happens in engineering studies. Anyways, you should get no lower than 96% in the general maths exam. Best of luck and I hope you get into your course!My school is ranked in the 500's :/
My ranks:
General Maths - 1/43
Engineering - 1/6
Construction VET - 1/13
Business Studies - 1/25
Advanced English - 1/12
My ATAR aim is 94+ so please tell me its possible aha.
