Hi Roy
the value of an MBA, in terms of career, is directly related to the reputation of the business school. This is why Harvard charge $100K, UCD charge €30K and DBS charge €7K. These fees aren't related to the cost of providing the mba - they are what students are willing to pay. You very much get what you pay for. The usual model for mba's in Europe is the executive model where you work for a couple of years, get some experience, and then do an mba. Given the field your niece is in this probably isn't feasible. I would advise doing the best ranked mba she can - the reward will be proportionate to the reputation of the business school.
