UK people only please... I'm from the US and am applying to UK universities for this year, so what I'm wondering about is early graduation.... here in the US we can take extra credits throughout semesters as well as during the summer in order to graduate early... we can also test out of classes. Can you do this in the UK?

I'm applying mostly to 3 year courses but am putting a 4 year foundation level course as a backup... Im planning on taking A-Levels in May/June for the 3 year courses I'm applying to, but if it's possible to graduate early I would prefer starting in a 4 year foundation level course and working hard to graduate in 3 years or less. Thank you for anyone who can help... I'm going to call around to universities later on today but thought I'd ask here also.
