Education Subject at uni

I'm leaning more towards the idea of maths with philosophy right now. Thinking that if I was spending 50% of my time on each, I could fairly easily transfer to Maths at any point if I decided philosophy was a waste of time, and if I wanted to get more into philosophy I could probably shift it more into philosophy while maintaining the maths element throughout the degree.

So hard to pick a 4 year course like this without tonnes of info on it though :/
