should i drop year 12 bio?

i'm currently doing two folio subjects (viscom and art cp) and whilst i haven't started my viscom folio yet, i'm already spending 5 hours min per week on my art one and know my viscom workload will be similar when we start our sat. i've already completed psych units 3&4 with a good study score that will probably be in my top 4 subjects, so bio is basically just an extra subject. i was originally going to keep it and just not prioritise it as much, but i feel like i'd regret not having the extra folio time if i didn't drop it (especially since the courses i want to do at uni are design/art based, and my folio is something they'll need to assess). if i dropped bio, i'd have an extra 4 free periods on top of the 4 i already have, giving me 8 hours for folio work in school which would be AMAZING. however, i'm not bad/failing at bio either (i was rank 1 last year) and so part of me thinks its a waste for me to drop it. but i'm genuinely just not enjoying the subject as much anymore tbh
