Whats easier A level geography or economics?

Geography GCE is sort of similar to GCSE. I personally think that geography might be easier if you did well in geography GCSE, rather than if you started a new subject like economics. But it depends on if you actually enjoyed geography or if you want to start something new. The subjects do overlap, a tiny bit, economics gets into the details whereas geography is more general.
Economics could be a good option if you wanted to pursue law though. It depends person to person. Look through some videos and past papers and see which of the two makes more sense to you. Shouldn't go into any a level subject expecting an A*, it is not like GCSE anymore, requires depth and understanding, but I'm sure you know that. 😜

I only got a 7 at gcse geography. I found it easy to understand but hard to memorise the huge chunks of case studies. and I absolutely hated physical geography it was honestly the worst. But I liked human geography. So i’m unsure on whether I should stick to it as an a level as I can’t do economics at the sixth form of my choice. Or go to a sixth form far away and do economics.

Only a 7? A 7 is great!
Physical geography is my least favourite as well, the human geography covered in A-Level (I do edexcel) is very interesting though.
If you struggled to memorise the case studies, I'll ask you a simple question - did you try to? If you did, then fair enough. But if you didn't use methods like flashcards, Cornell notes, practicing exam papers, etc. then you'll see that it isn't as difficult to remember as you think. Honestly, my friends make up their figures. The main part of case studies is being able to apply them properly in a concise way for an argument or evidence.
Physical geography is a key component, but I wouldn't let it deter you too much from continuing with geography. There are new topics that aren't covered at GCSE, like for me I didn't do tectonics nor the carbon cycle but now I am. You could find that you do (at least somewhat) enjoy a physical subject, just one you haven't studied before.
It's tough to decide on whether or not to travel to 6th form. Are there ANY other options which are closer by? Economics could be a good choice, it is quite respected as an A-Level and makes you think more critically. It's like geography but up-to-date and TODAY. It's analysing behaviour of firms, the government and consumers, which is quite similar to geography in some respects. Fortunately for you there are no rivers or rock type topics in Economics.
My friend travels everyday for 40 minutes on the train to get to school. Quite a few people in my school do. How good is that school you COULD go to? If it isn't a very good one then I'm not sure. I wouldn't worry about the social bit of travelling far, friends aren't too important in 6th IMO. Equally they're not too difficult to make, there's always going to be SOMEONE else in the same boat as you.
How far away is far away?
