it was AS level maths but you have to able to apply it it in extremely unfamiliar situations, much like the MAT. if you've been preparing for the MAT the maths questions should be doable. the programming questions depend on your level of programming ability. for beginner or new programmers you need to be able to grasp the info they give you on the codes very quickly and answer the questions. with a lot of programming experience these questions should not be too hard. in my opinion this admissions test is harder than oxford's MAT which I'm preparing for because the 45 minute time limit I thought really affected my performance and I could've done a lot better if it were a one hour test. But at the end of the day that's how you separate and filter put candidates, if I'm good enough I'll be called for an interview, if not it is what it is and I wish who ever got that interview instead of me the best of luck
