Also how much maths is involved in an economics or finance degree
Finance degrees vary widely, some are just business/management degrees with a slight focus on accounting and/or finance, while others are very mathematical. The more mathematical ones will normally require A-level Maths, and will probably be similarly mathematical to an economics degree in terms of the frequency with which you'll be doing mathematical work. The less mathematical courses however may not include much mathematical content and it may not be far beyond GCSE level maths. For this option you will need to carefully investigate the course content for each course individually.
In both of those there is maths, but with economics you would just do a Ba course. Unsure on fiance as i do Economics. Those are fine choices, i did the same bar English, for which it did ICT. You are just slightled limited in terms of going to top top uni's like Oxford, LSE etc, but you can still get into Nottingham, Birmingham Leeds so it's fine. Just so long as you passed GCSE maths you'll be fine.
Honestly it depends on what you want to get into. Most jobs won't care, i would say try to do an econometrics module, that is the key in my opinion, just so you have the basics of econometrics, as some higher end jobs do care about that A few jobs may want maths at A-Levels, but i'm applying for graduate roles now, and that number is less than 5%
