Can you choose physical or human? Which would probably be easier? I live in a small town with some surrounding villages and a few larger towns so it might be harder to get a large sample size for human.
I do have rivers and the coast near me which would make physical easier but just concerned I wouldn't have enough to talk about. For GCSE, it was so much easier to talk about the human fieldwork and the mistakes and all of that.
What topics would you recommend?
