Dear aspirant ,

In some colleges and universities for MBA , a student applying for MBA outside the country have to give GMAT exam . Students applying for MBA in England have to give GMAT exam , it is compulsory . However , there are some universities in England in which it is not compulsory to give GMAT exam  instead of it students having a work experience for more than 2 years can apply directly for MBA program . In Germany most universities accept TOEFL score and not GMAT score , there are universities which accept both TOEFL and GMAT score .  In Poland all types of entrance exams are accepted like TOEFL , IELTS and GMAT . So  for betterment of you , you should first choose a country for which you want to study MBA and then second look at the eligibility criteria at different universities and according to that give a appropriate entrance exam . Also you can do is that choose a university of that country and then check which entrance exams for MBA they accept .

Hope it helps.
