Thank you so much for your suggestion! I'll apply for good-ranking business school like Cardiff, Manchester, Warwick, etc. But also because of my budget, if I live in Brighton with my friend then I can cut down most of my rent.... Is the business courses there really not so good?
I do have a purpose by setting up a social enterprise, I want to change the way the world tackles poverty, especially for youth. Haven't got a clear idea how to make it though.
About social marketing, it's just one of the extra modules that I can choose from that Entrepreneurship management course. Because most of the core modules are already about how to make money, I was thinking probably I should also study something else from a different aspect. But If I really go there to study, I'll ask for details about it before choosing. =)
