I think I've already answered this but things changed

I did:
yr 11: revolutions, further maths
yr 12: Japanese, methods, english, psych, bio
I also did: 1/2 chem, so psych and bio I didn't do 1/2 for.
I wouldn't change any of my subjects at all.
6 months ago I would have said I wish I hadn't of done biology, but now that I'm at uni I'm really enjoying it and I'm so glad that I stuck with it, even if I did find it difficult at first. I also found methods really difficult towards the end but doing it made me a stronger person and gave me future options I hadn't even considered.
I'm naturally an english/humanities person and I remember saying that I shouldn't have done any science. I WAS WRONG. Sometimes it's worth doing things that don't come easy to you (not all the time) and you might enjoy the challenge. Saying that though, revs was extremely interesting and changed my thinking, similar to how psych did. I'm also glad that I didn't do chem in year 12 (weirdly) because now I'm doing it at uni and am actually enjoying it because I don't have teachers that hate their jobs.
