Please be careful when considering a foundation to Access course. As other posters have said, some courses/universities specify specific GCSE grades and do not accept equivalent level 2 qualifications.
As a prime example there was a guy on my Access course that completed the level 2 Access the previous year, he wanted to study nursing (specifically ODP), but was told by all the universities he spoke to that the level 2 qualification was not equivalent to GCSE and that they would not consider his application unless he had the appropriate GCSE qualifications.
I would urge you to consider carefully what you wish to study at university. Once you have decided, I would shortlist the universities you would like to attend, then contact them directly and ask if they accept equivalent level 2 qualifications.
Good luck.
