Hello Kalyani, it's very nice to hear from you that you are interested in doing your graduation in engineering after completion of your Diploma in engineering. You can get admission directly into second year of 4 years engineering graduation course. This is called lateral admission process. Else you can think of Diploma as equivalent to 12th and appear for JEE Mains examination to have a shot at admission in NIT or IIT. Best wishes to you.

You can do this. Few good MBA specializations could be -
- marketing
- IT
- HR
You can do this in regular mode from reputed b school or through distance mode from IGNOU/ Symbosis/ NMIMS/ KUK / LPU/ ANAMALI etc. Also you can explore about options of executive MBA from top b school like IIM, XLRI, FMS etc. Best wishes.
