Hi there!
I am year 11 and am currently taking both geography and history (although both AQA). Personally, I have found history so much more interesting than geography (which very quickly became very repetitive) and I have enjoyed the lessons and revision much more. However, I have found history much more difficult both due to the question types (although may be different with OCR!) and the huge quantity of dates and facts to just purely memorise.
Although, if I had only taken history and not geography I imagine this would have been less of an issue as it was combined with memorising facts from geography which I needed too.
Personally, if I had to choose between them, I would choose history but I have had a brilliant teacher and super interesting topics (medicine, Elizabeth I, Vietnam and Korea, and Germany). However, I do think geography is considerably easier!
Neither of them would be a negative choice (in my opinion)!
Also bear in mind if you have any desire to do either at A Level, obviously go for that one! And keep in mind I do a different exam board to you and I am by no means a historian or geographer 😂.
Good luck with your choices!
