Hey
thought I would help you out again as you seem an eager beaver and I can imagine being in your shoes and being excited about studying and could do with someone to help!
Everyone has different experiences and opinions so asking might end with asking more questions than before.
The best thing you can do is to google each university and watch videos and note down what you liked about the university and also search for things at these cities that are interesting to you, its location, stuff to do etc.
As I said before, Oxford could be really interesting and different to many other cities and towns or campuses, and has a shuttle bus to London which is really cheap.
The idea of doing something more business / generically based could work as it would give you more options such as studying in London which is is really a great experience for a young person as there is so much to do considering somewhere like Queen Mary, University of London for something like M.Sc. Management or M.A. Marketing at Royal Holloway, University of London (in Egham, Surrey) as the London brand is strong and considered to give a better student experience and graduate employment prospects.
The best thing to do is look at the Complete University Guide:
http://www.thecompleteuniversityguide.co.uk/league-tables/rankings which is the best for understanding where the universities are ranked as people seem to look at undergraduate rankings for the overall ranking for considering postgraduate studies, basically if you care about ranking then let that sway your decision but if the course is unique and specialised then ranking doesnt really matter.
You will see Surrey is ranked #11 and Exeter is #13, so both great universities to consider.
I think the University of Surrey is something to seriously consider for it is a great university on a quiet and beautiful campus which is near London to travel to easily and cheaply, 40 minute journey for £10, you will find the housing to be really cheap compared to London prices and the Surrey area is a really nice area, if you look on Google maps you will see the Surrey area has some of the nicest houses in the UK, and you will find University of Surrey has a lot of middle-class, connected, wealthier and bright and intelligent people there to complement its ranking as top ten.
The other universities are all considered of equal consideration its only the top 20 universities that people fight for places.
Have a look on
Rightmove Student Accommodation which is a good place to get an idea of housing prices.
I've just had a look at firstprotocol again and
found a lady who works for Goldman through firstprotocol and seems like the exact sort of thing you want to be aiming for.
Simply, I would say Surrey and then head into the City of London to work in hospitality for the banks like
Rothschild, or
Man Group which is the largest hedge fund in the world, UBS,
Deutsche Bank or technology like
Google or Apple with product launches etc.
.. and if you really wanted to do something spectacular.. how about t
he Royal Household.
Now that would be an event I would like to plan and manage! Heads of state... yikes!
Hope this helps.. any questions do ask
