Which Accreditation you would like to know is it AMBA?
for MBA NO
but for MSc Yes.
You can also try for Strathclyde MBM which will lead to MBA in future.

I would suggest Cardiff MBA which AMBA Accredited and does not require Work Ex.

You can look for AMBA accredited MBM programmes here: http://www.mbaworld.com/guidetomba/searchbschoolmbaprogrammes and and for EFMD recognised EPAS programmes here http://www.efmd.org/index.php/accreditation-/epas-/accredited-programmes

An MBA program that does not require work experience is not worth doing. The main purpose of doing an MBA program is to build on and to develop your work skills - and if you have no work skills, there is absolutely no reason to do an MBA!

All it takes for many schools is two years of work experience - I'd suggest at least trying to do the minimum and then applying for an MBA program.
