Get the Foundation Art done, as it'll help you a hell of alot later on once you finish your degree at Bournemouth.
I did kind of plan to go to Bournemouth and do that exact same course as you listed above, but the entry requirements are 300 UCAs points plus at least a B in GCSE Maths; the maths will be needed because the course is more technically focused, requiring you to program plug-ins, etc.
I missed out on a B in my maths during GCSE, and the most UCAs points I'll probably achieve once I finish my BTEC diploma this year is 200 from a Merit/Merit/Pass, and then add another 30 onto that from a previous AS level a few years back which puts Bournemouth just out of my reach.
The Uni's that I'm interested in going to (in order) are Lincoln, Huddersfield, and Staffordshire..................I just hope my last year at college goes better than I'm expecting.
