G Hi I read through your subjects and realized I'm trying to do almost the exact same, what math did u end up picking? I had to make the same decision and it really wasn't easy, I just went with the thought that if it gets too terrible I can always drop down to general and methods. I'm trying to do (French, Lit, Spec, Methods, Physics and I've advanced into Bio this year, so it'll finish early)
It might be a bit late but I really enjoy bio, despite the non-existent scaling. I think if u have time to put into it you can still get a really good study score, and if not it can just sit in your bottom 2. So far I've gotten 89, 96, 97, 97, 100 on my SACS, with a bit of effort and understanding how the mark distribution works it is possible. But that might just be my experience with bio so far.
Best of luck
