Hi lm21074!
Welcome to the forums
I think Quantum44's suggestion is great. Bio & Psych are certainly great subjects to do early - they can be quite content heavy and so doing them early lets you devote a bit more time to them
They are certainly popular subjects to do as 1/2s in Year 10 then 3/4s in Year 11.
I think you should also base your selection off what you think you're good at, and what you think you'll enjoy doing the most
I would perhaps suggest leaving English Language, Chem & Methods to do in Year 12 - personally, I think having that extra bit of maturity from doing them when you're one year older will have an added benefit. That being said though, there are a fair few students who choose to do Methods early - I think though, to make that decision, you'd want to be quite strong in Methods (personally, I couldn't have imagined doing Methods early, I struggled enough with it in Year 12!
I think it's definitely a subject where you benefit from being a year older when you do it). Particularly for Chem, a lot of schools actually don't let students do the subject early, because students really need an understanding of the basics of Chem as well as 1&2 under their belts before they tackle it, as well as for a few other reasons.
Legal Studies could be another one to consider doing as a 1/2 in Year 10 then 3/4 in Year 11. I think humanities subjects can be great to do early (I might be a little biased here, having done History as my accelerated subject
), because they have lots of content to memorise/learn, and so doing them early means you can dedicate more time to them. I believe it also allows the subject to become much more enjoyable and less stressful
I'd recommend going and having a chat with your careers advisor at school, some teachers of the subjects you're looking at doing, or your year level coordinator
Their help can be invaluable, and they can give you personalised advice because they know you much better than we do.
All the best!
