diploma's are more targeted, hence for some like me it's great, also you're more free and respected (well depends on teachers and college i suppose) but you're not going to be treated like little mike still by your teachers at school if you stay in sixth form
as mentioned more targeted, usually have more money and better equipment also, more help offered with unions and financial advisor's etc.
I doubt they do A-Level Multimedia Graphics Illustration Video Editing and Animation (a basic run down of my current course) hell my school still ran win 2000 and didn't have any apps other than office
