I'll update this post from time to time to add in new schools identified, but I've started off with all the schools in the FT Global MBA 2011 ranking, and a few more.
Different programmes welcome applicants with degrees in business, or only those with degrees in other subjects, or both. Thanks to Ralph for pointing that division out.
