Hello gerjapa,
The average GMAT score for the MMM program is around 650. So a GMAT score of 650+ is always going to be a plus point.
The MMBR program is new so I cannot say what the average GMAT score is going to be. But the minimum GMAT score requirement is 630.
Best of luck for your application!
Here are some points you may want to consider-
• The MMM program is the flagship program of University of Mannheim whereas the MMBR program is new program.
• The MMBR program is more research driven and is suitable for someone who wants to pursue a doctorate degree.
• An application essay (maximum 10 pages, A4 size, font size 12) is required for the MMBR program whereas no application essay is required for the MMM program.
• The MMBR program is taught completely in English whereas the MMM program has an option of mixed track (English+German).
