Which should I choose?Watch
Universities and jobs will look at your a-levels and degree far more than GCSEs. Like for me, I don’t even list what my GCSEs are even in now (aside from English and maths) because it doesn’t matter as much. Just pick what you are interested in and what you think you can get the best grade in because that will be more important in the long run.
Unless you want to do, let's say a geography degree in which case you're going to need that GCSE geography to do A Level geography to do a geography degree.
