So as a Year 11 student, aspiring to achieve a high ATAR next year (98-99), my units for the HSC are Biology, Chemistry, English Advanced, Mathematics Extension 1, IPT (Accelerated - Meaning I am doing the HSC for this subject this year in Year 11), and then I am deciding between Mathematics Advanced or Mathematics Extension 2 (dropping Advanced for HSC)? I am wondering which I should choose, as when I go on to ATAR calculators (I am well aware they may not be accurate, scaling changes each year, I am still in Year 11 I technically shouldn't be worrying about this, I have no idea what my marks will be scaled or raw or aligned, etc.), I see that with the same marks for each subject, when I put Maths Extension 2, I get around 98.75 - 99.1, but when I replace that with Maths Advanced I get 99.7-99.95, but my tutors are all saying Extension 2 is better, and scales better if I do well in it, and I should choose it. I am conflicted, and wondering why this is occurring, and what you recommend.
