Leeds Digital Media

I've applied for 2 courses at the University of Leeds: 1. Business + Marketing (preferred) or 2. Digital Media

I don't think I'll get an offer for the marketing course as is AAA (I might be provided a reduced contextual offer but we'll see)

I wanted to know what the Digital Media course is like, or how easy it would be to swap from Digital Media to Business + Marketing

Marketing is the career I want, Leeds is probably my favourite choice and I need to know if it's better to do Digital Media there or go somewhere else such as York or Lancaster to do a straight up marketing degree

I don't know much about the marketing degree, but digital media will absolutely be able to get you a career in marketing if that's your future career, you'd just learn different skills that you wouldn't in the business school and vice versa.
Digital media looks closely at design, websites and the the interactions of people in online spaces. A majority of those on the course will go on to do digital marketing. It would be more creative than a marketing degree and won't focus as much on things such as economics.
A business degree and a communications degree is very different. Digital media will be more practical. You will have FREE access to the creative cloud for the whole of your degree, which gives you the chance to freelance in your spare time.

Again don't know much about marketing degrees, but digital media could be a very good option if you have your heart set on Leeds.
