Is AQA Economics A level a good subject to take?

My advice is do it if you enjoy it. I've applied to Biology and Chemistry A-level next year and I started having doubts because sciences are so notoriously hard. But, I've come to the conclusion that I love science, so I know no matter how hard it gets I'll keep going because its something I enjoy, and I don't want to fail it. I don't see the point changing subjects just because you'll think it'll be 'easier', because you probably won't enjoy it and then you would work as hard. But, if you think you'll enjoy another subject over economics, do that instead. All A-levels are hard! So do something you'll be comfortable and even enjoy studying.
Hope this helps!

I haven’t started economics yet and I don’t know if I’ll enjoy it because I’ve never tried it

What other A level subjects are you planning to take?
What degree subject are you aiming at - any ideas yet?

Maybe take a look at the specification for the exam board(s) that your colleges/sixth forms offer for economics? That would give you a good idea of what you’d be studying so you can determine if it’s for you or not. Also, maybe go onto YouTube and search up “Should I do A-level economics?” So you can hear about people’s experiences doing the subject to help you decide. Plus, like McGinger said, think about whether or not economics would help with the degree(s) or career(s) you are interested in.

Economics would probably help accounting and finance at Uni. And if you don’t want to do AQA, you can find a school that does a different exam board perhaps? If you struggle with the long questions I’m sure your teachers can help you excel them!
