I suggest that anyone answering you looks first at the other posts on which you have commented (See http://www.find-mba.com/about/sidsingh2 ) since any reply might replicate a lot of what others have already written. The rankings (you will need to look at previous but recent years' rankings to get comparative data) show the faculty and career strength of the programmes. Durham is widely discussed on this board as being academic rather than applied in style. Strathclyde and Aston have very different curricula.

Avoid Aston, I am here now. They only got 6 internships total and 1 went to exchange student. 3 good professors have left. Most of this year cohort left after classes everyone hates experience. Only people getting jobs are with former employers. School is a joke.
