If you are asking for a graduation course which will enhance the scope of MBA you will to do in future, I suggest you to go for courses like BBA or B.tech as there value is increased as well as they increase the value of MBA when done by a person before pursuing MBA. You can also go for B.com or B.com Hons. for your graduation, these were the courses which are most suitable and demanding with MBA.
