I'm currently writing my personal statement for maths. Loads of examples I've seen mention doing maths challenges and olympiads- which I haven't done. It has made me a bit demotivated because I will be competing with people who have hard evidence that they are good a math whilst I only have done math tutoring, some further reading, a bit of coding, and I'm currently involved in a math programme in my local uni.
Are these experiences sufficient enough to apply to Bristol, Birmingham, Manchester and Loughborough? Or would I be put at a disadvantage because I haven't done any olympiads and stuff like that?
