Say your birthday was in September then you would be 19 when starting uni, 20 if having done a gap year!
then if you did a 4 year programme with a placement year, you would be 24, turning 25 at the end of summer and merely a few weeks after starting a graduate programme in July / August, with some starting in September to give you the summer to have some fun.
You shouldn't have any problems with your career as long as you can show why you did what you did when you did it so being realistic.. how much of a better uni do you think you will get in to with going to college? Probably not much, and although people assume the best universities are the obvious ones like Oxford and Cambridge when actually some specialisms are at lower ranked universities. Advertising for example, huge industry worth billions yet the best course for
advertising is at London College for Communication, part of the University of the Arts. Somewhere like this might be much more suited for you than somewhere elitist and stuffy like Oxford.
You mention Politics and Economics.. well in the political realm is a lot about public relations and political consultancy / strategic communications / crisis management whatnot. There is a revolving door between government and the PR industry. LCC offers a great course in
public relations or over at
Cardiff there is Journalism, Communications and Politics and this a great mix of how the media has so much power to influence the world - take the shootings in the last few days and how the aspect of live-streaming, not just uploading a video but actually inviting the internet to be with when something crazy like that happens can have a huge impact of tens of thousands of people marching in protest all over the world.
Cardiff offers modules such as:
Introduction to Government and also Political Thought and Political Science,
Representations
Influencing Public Policy,
War Politics and Propaganda,
Citizen Media
The Making and Shaping of News
Communicating Causes
Elections in the UK
Spin and Unspun: Public Relations and the News Media
Cardiff is ranked 35th nothing spectacular but a good university and would open doors, so no point fighting for a better uni when you can do so well in other places as I have tried to demonstrate. The advertising course at LCC for example could have you working for
Ogilvy & Mather in London and then on to New York! They recognise the prestige of the advertising course at LCC within the advertising industry.
The degree from Cardiff could get into newspapers, government, PR, and also within financial services so to build experience in all these areas would make your profile stronger and perspective on all of these collaborating industries.
This is so much more interesting and modern to
studying PPE which has created a robotic governing class.
So this is to go to show that if you research and think of a clever way to start your career it could be really interesting! Entirely up to you but really doing your research might really help and finding out what you can do with what you've got so far would be good and how you can work with that.
Anything else just ask.
