Hey, I'm having a similar problem in that I seriously can't decide what subjects to drop/pick up for year 12 this year.
My current subjects (for year 11 and the start of term 4 [term 1 year 12]) are Advanced English, Extension 1 English, Advanced Maths, Chemistry, Biology, PDHPE and Modern History.
I'm currently performing in the A/B range for all my subjects (except maths which I need to work on - and I need to keep because it is a prerequisite for my course; Medicine).
I was thinking of picking up Ext 2 English and Science Extension just to prevent regrets of not choosing them + they sound pretty cool.
Some recommendations have been to stay as I am with my 13 units, others have said to drop Modern because apparently, it doesn't scale well (also, is it true that PDHPE and Modern are 'low-scaling' subjects - I don't want them to drag down my ATAR since I've heard that people with total marks of 96 have had their scaled mark be 90 or lower in these subjects), and I think that maybe I should pick up Science Extension as - according to my Careers Adviser, 'Medical Schools'/Universities that offer Medicine look for those with the highest ATARs and the 'most' science subjects since it's such a competitive course.
But Ext. 2 English also sounds really fun.
Would you recommend starting with 15 units (which is quite a lot) and dropping subjects as I go?
Or will that just be too stressful + take time away from my other subjects?
Any advice?
Thanks!
