On the websites of many US b-schools, it was written clearly that bachelor degree is one of the general requirements. So you may ask the schools that you want to apply to, I suppose you will have to explain why you did not have the bachelor degree( like a essay). The school authority may suspect why you did not have a degree. But as long as you have a just cause, you may have chance!For the b-schools in UK and other countries in Europe, you can apply to b-school even ifyou do not have bachelor degree!Anyway, wish you best of luck!
