I'm in year 12 right now, I was wondering what choices of work experiences involving maths. I'm thinking of doing maths for uni. Is there any recommendations or websites I could do work experience for July in London?
Young Professionals - sign up to the young professionals mailing list. they have events, some in person and some online and they give you some work experience you can put on linkedin. They're also useful because you can see what jobs appeal to you when they send you info about events in which you can learn about different companies
No Uni will require work experience for a Maths degree.
So, you can either just 'get a job' - any job - to earn some cash and get used to being at work, or you can work on academic stuff to boost your Personal Statement.
