Personally there were a few VCAA studies I really wanted to choose but couldn't, either because they weren't offered by my school or I didn't have space. It'd be interesting to see if anyone else had the same experience, and for what reasons.
My current subjects are Lit, English, Methods, Chem, Media and Politics, but ideally I would have loved to have done Lit, Classics, Politics, Philosophy, Latin and Theatre Studies, and potentially a uni subject too, or Music Performance.
I've found that I enjoy Chem and Media in a way I would have never realised under different circumstances, but Methods and English bore me to tears.
So yeah, your turn. Discount anything like uni prerequisites, parental pressure and even the English requirement, if you want :p
