I am a chemical engineering student and i aim to further my studies in management and entrepreneurship in the UK. I understand the dilemma between MBA with no accreditation and Msc in management.

Can you help me find masters in management in prestigious universities without a GMAT score ?

Thank you

Many prestigious universities don't have great business schools, so I would start with those. Maybe Bristol, Queen Mary, St Andrews, Surrey, York, Southampton, UEA, Sussex, Cardiff... http://www.topuniversities.com/university-rankings/world-university-rankings/2015#sorting=rank+region=+country=208+faculty=+stars=false+search=

Thank you
What about Bath , wawrick , LSE ? Are they good in management and business or just there selecting criteria are hugh to reach ?

No, I don't think they require the GMAT although Warwick certainly favours the GMAT strongly.

Thank you Duncan , to be honest with you I think that schools as Wawrick , LSE , LBS , Imprerial ... are difficult for me to reach because I don't have any business background. My candidature will be poor among those candidates who are willing to study in such prestigious universities. My English muches management programs.

are The universities that you suggested still good schools with international accreditation and respected by employers ?

Thank you

If employers are what matter then focus on the schools in the FT MiM ranking.

If, by "business background," you mean that you did not do a bachelor's in business, I do not actually think this is a handicap. For instance, the LBS MiM program only looks for a UK 2:1 degree in any discipline.

Yes , I have a scientific background . Is the MiM at LSE a good choice ? Thank you

Why not look at the schools in the FT MiM ranking? A lot of good UK options there - Imperial, Cass, Warwick, even Bradford, Manchester...

You'll most likely need to take the GMAT though.
