Cambridge and Warwick universities generally require candidates to sit one or more of the STEP papers and achieve certain grades as part of a conditional offer to study Maths (or Maths related courses).
Other universities, including Bath, Bristol, Imperial College London, King’s College London, Loughborough, Nottingham, Southampton and UCL may take STEP results into account when offering places.
Even if they are not mandatory I would encourage students intending to study Maths at university to attempt STEP. It is excellent preparation for degree level thinking and is designed to test candidates on questions that are similar in style to undergraduate mathematics.
STEP I and II are based on the now standardised material in A-level Maths, though STEP II is considerably more challenging than STEP I. STEP III requires Further Maths theory and given the module options available from the examination boards, students are not expected to be in a position to attempt all of the questions. Students are assessed on only best six questions attempted in each 3 hour exam, so the time that can be allocated to a question is likely to be significantly more than experienced at A-level.
