It is generally 2 years for General or distance MBA, 1 year for executive MBA and 5 Years of BBA-MBA integrative courses, but these may vary.
But to answer in reality, anyone can get an MBA degree from an institute in 1/2/5 years, but to become a real MBA you got to have the mentality of the manager. The Degree wont count until you prove yourself to be an MBA. 🙂
