I did biology, chemistry and geography. But you could always do bio/geography without chemistry, you can still get into medicine with just biology. It may only be specific universities so it’s worth having a look. I enjoyed A level geography+I enjoyed it at GCSE, it wasn’t much different in terms of human geography+ I found the content more enjoyable. I think I got lucky because I did glaciers and not rivers/coasts. I think there may be a minority (but there’s still some) of medical schools that accept chemistry without biology, so it’s good to look as well. It really depends on what university you want to go to tbh. Good luck with everything.
