Hi

In an MBA-MS dual degree course, a student gets both the degrees after a three year course. The idea behind it to offer a student both technical and management know-how.

The scope of such degrees can't be quantified but the purpose is that is has become of utmost importance for individuals to be able to do their work and manage people under them. Hence, the dual degree course.A few good colleges to consider for the course are 

•  Yale school of management 
• FGV escola de Administracao de Empresas De paulo, Brazil
• HEC, Paris
• Hong Kong University of Science and Technology Business School
• Sauder School of Business at University of British Columbia, Canada
• Stanford Graduate School of Business

All the best!
