Cam I do an MBA without a bachelors degree ?

I don't believe the good colleges in India allow students to apply for an MBA without a bachelors degree. You can apply through a GMAT score to foreign universities provided everything else on your profile is solid. This will include an excellent GMAT score, good LORs from multiple professionals and a solid reason why you do not have a undergraduate degree. The reason should be genuine, such as you might have joined the family business or started your own venture. If your application is genuine and you have a solid reason to account for the lack of an undergraduate degree, there is a ggod chance you'll get accepted for an MBA program.
