Hi,

Single course and double course MBA are both good in their own perspectives but there lies disadvantages as well. While pursuing single course MBA, you can focus on one subject but the learning spectrum is limited to that area while for dual you get to learn more and have a diverse knowledge. But on the other hand while pusuing the double course, you will have to pay a higher price for studies as compared to the other. Also companies may give you pretty much the same salary as someone pursuing a single course MBA despite having a dual degree.

Hope this helps.
