You need to be qualified for the overall programme. This relates mainly to the number of GCSEs you have passed at grades A* to C, but can also depend on English GCSE and other results.
Most individual courses have their own entry requirements (for example, requiring a grade B in a particular GCSE).
For guidance on all entry requirements, please start at our programmes page. This takes you through the process of choosing a programme, followed by choosing the individial courses within the programme.
