None of these are excellent options, as you know. I think you can rule our Exeter because its OneWorld MBA is aimed at the charity sector. Unlike Southampton, Aston is a long-established MBA school with a good profile with MBA employers. It will have better connections with MBA employers. Birmingham is a bigger city with more opportunities and a large conurbation around it. However, a better programme, especially one that requires the GMAT, will give you a much better chance with employers.

Go for Aston. It has a pretty good reputation in the field of business. However, it is not one of the schools that is well known for its MBA.

Thank you for all comments and you are very helpful.

However, since I got budgetary and academic background reasons limited, therefore, there are the only three choices left I have to choose and I probably go to Aston U. since it is well-known for MBA as advise. But, I'm curious why Aston U. both MBA and overall ranking are significantly dropped? Sometimes I feel like studying in a large top ranking university but chosen course is not outstanding may somehow raise your profile in resume most or least?

Thank you :)

For the MBA I'd speculate that it's because it tends to recruit a lot of younger international students who have trouble finding work in the UK after graduation, and as such the post-MBA salary stats aren't as good as at other schools.

The last year it was ranked in the FT (in 2012) its post-MBA salaries were the lowest of any UK schools in that ranking. And at that point the salaries had dropped quite a bit from the previous time it was ranked in 2010.
