Distance

Hi Bhuvan,
The best choice would be to pursue regular MBA, but if you want to do MBA through distance, go for it. It is also a good choice.

If you are a graduate or in last year of graduation (as per norms, it can vary). Sometimes, you can apply for government jobs at class 12th level also.

You shouldn't go for distance education especially if you're interested in doing B.Tech, instead you can take admission in UTM Shillong. UTM is actually MIT Pune's campus and is best in North East for their Engineering programme.
If you want to take a look at their website do visit -www.utm.ac.in

Yes, if you are working and want to do MBA you can do it through distance education.
