I've done a Diploma in electrical engineering. Is it possible to do MBA after Diploma from a private institute? Is it worth?

Dear Chirag, In order to do MBA, you must have to recognized "degree" from a university. The duration of this degree should be of minimum 3-4 years. And you must have more than 50%-60% aggregate in your graduation. Since your Diploma will not be consider as a degree, you may not qualify for MBA.
