Hey !

As your query is regarding the entrance exams and the other deatils to pursue MBA in other countries,here it goes :

Unlike in  India, Foreign MBA requirements are quite different from our MBA programs. The first and foremost eligibility requirement is to have completed a basic bachelors level graduation degree. This could be an engineering degree (B.E, B.Tech), B.Sc, B.Com, B.A. or in any other discipline. A Masters or doctoral (PhD) degree is also fine. MBA colleges in Abroad give a lot of importance to work experience(not only technical but also managerial). HBS,MIT,NYU are some of the top colleges which accept students without prior work experience. Coming to the exams for intake of students,the two primary exams are GMAT and GRE.  Though GRE is most popular in MS applicants, things are changing and many MBA universities have started accepting GRE scores. GMAT anyhow was always been accepted.TOEFL and IELTS are two popular exams that are accepted by international business schools across the world. CANADA,UK,GERMANY,USA stand at the top in countries offering MBA. Top rated colleges are:

1)Harvard Business School

2)Stanford Univ GSB

3)IMD Switzerland etc
