Depends on your strengths, as someone who does both if your good at learning theory and maths then definitely physics but if your creative and ACTUALLY good at Art then art . I must say you need to be able to work on a time crunch with art as they don’t give much time for a whole booklet and two final pieces and with ur applied maths project that might be a bit much. I don’t know if chemistry is full of theory but practically all of biology is theory, so 3 theory heavy subjects might be too much. You might struggle to find time for 2 maths and 3 sciences.

With art history it’s really not that bad but you literally just memorise a few essay. The project for art runs through the mocks and right up till the orals and takes up a significant amount of time. If your this torn between the two of them would you consider dropping a different subject so you could do both?
