I got in with a B in gcse maths even though the requirement says A. There is 0 maths content on the course so I honestly don't know why they choose to put A as the requirement. We have stats modules but we use a programme which does all the maths for us so again, a B is perfectly acceptable. Take your chances and apply, I wasn't sure they would accept me with a B but they did. I will be going in to my final year in September, I am currently on placement (where I still don't need an A in maths)
