It will depend on the college. Basically until now, Access courses included level 2 (GCSE equivalent) Maths. However, universities have stopped accepting this as GCSE equivalent (understandably to be honest - I've just finished my Access course and the level 2 Maths was far, far easier than GCSEs). This means that if you are applying for courses that require GCSE Maths and English, you will have to take the actual GCSEs, not just the level 2 equivalents that were formerly part of the access course. Obviously some Access students will already have these and some won't, so they can't really completely integrate it into the course, but for example my old college is running the GCSE Maths and English courses one day a week, purely for students on the Access course who need these qualifications, so you can take them alongside the Access. Obviously different colleges will approach it differently, but the change in university requirements are what has prompted this change in the Access courses.
