Hi,
My name is Eleni and I'm from Greece.
I have been accepted at the University of York (Msc in Finance) and also at Bristol University (MSc in Economics&Finance).Which university do you think it's better?? The only thing that i prefer at York university is the programme structure but still i can't deside.

Have you checked the various University rankings?

The better thing you can do is to categories the best universities. As per the rank of universities you can choose one of them. You should check out ranking of universities.
