The answer is almost certainly Birmingham. If you are applying for both part time and full time programmes then you want to leave your company and perhaps change industry. The full time programme will be better unless you want to stay in your industry and current location. If that is the case then go to Cass.

I'd generally agree with Duncan - the Cass program is quite different from the others, and the decision pretty much hinges on your future career goals. If you're planning on staying in Dubai after graduation, you might find that staying in Dubai will give you more networking opportunities - although you'd miss some career services resources.

All other things being equal, Birmingham will probably provide a better value than Aston. However, if you're looking to find a job in the information technology sector, a case can be made for Aston.

Birmingham MBA is more strong than Aston. but CASS has more brand value. To be honest it depends on your current circumstances, since the job opportunities are not very promising in the UK, Its better to do it from Dubai it self.
