Distance

Hello Lalit,
It's the best to pursue your passion even if it's outside engineering. Yes, geography is a good choice. I feel that your best option would be IGNOU. It's distance education programmes are world class.

Dear Priyanka Vishnoi,
If you really want to pursue the worth programme, consider NMIMS-Mumbai, Prince Wellingkar-Mumbai and Symbiosis-Pune that are offering MBA finance. Just go through it.
All the best.

Dear Vaibhav,
NET examination would be conducted by University Grants Commission, New Delhi, which expects a full Master's degree in various disciplines, with post graduate Diplomas you cannot take the entrance examination for lectureship or for research fellowship. BUT there is other chance for you, IIMs offer FPM, Fellow Programme in Management equivalent to PhD. With PG diploma you can do FPM programme.
