I have an Arts degree/I haven done maths for years. Is that OK?
The subject of your first degree is not important. Many of our students have an Arts background. They do just as well on the course as those with a Science background. The course makes few assumptions about your previous studies. In particular, you are not required to know any mathematics beyond GCSE (previously ‘O’ level). There is theoretical material in the course but we teach you what you need to know.
