Can anyone rate MBA provided by university of bolton

You can see a list of accredited MBAs here:

They will be much better.

Bolton is the fourth-worse British university: http://www.guardian.co.uk/education/table/2011/may/17/university-league-table-2012

Bolton will probably not provide that great of an education. As far as I know, there are no good programs in RAK, and few part time programs in UAE in general. Why not check out United Arab Emirates University's program in Al Ain?
