Hi,
By clearing +2 certificate, you can do first Diploma Engineering followed by B.Tech in lateral entry in 2nd year. After B.Tech you can do MBA/PGDM cracking competitive exam for management entrance. But if we consider practical implementation of above route for you it is, though not impossible but difficult unless you become really serious, sincere and methodical in your study.

See, an online MBA particularly from India is not so worth considering quality of the content and curriculum. MBA, being a management subject need lot of activity such as presentation, case analysis, role play, study, sharing what you do and what others do, working with different team, etc. Therefore instead of a distance or an online MBA, a part time MBA from a good institute such as FMS-Delhi, JNTU-Hyderabad, NMIMS from its various campuses make lot of sense and value addition.
Alternatively, you may opt for various MOOC courses from world class universities and they are better than a distance/ online MBA.
