good luck! Honestly don't worry about the grades. As long as you pass Maths and English you can get into college/get jobs (although you'll need science GCSEs for some jobs/you'll need to pass any subjects you want to study to college if you want to go)

Your GCSEs don't need to be higher than passes (or your college's grade requirements) for uni either, that'll all depend on A Levels (although Medicine degrees and Oxbridge students (and possibly other really prestigious unis) require you get good GCSEs)

What's next for you once you've got your GCSEs? I'd ask what you chose for GCSEs but I guess I'll find out later
