B.Sc

You need to do D.El.Ed to be eligible for this exam. You can pursue D.El.Ed from NIOS very easily though.

Hii Sriniwas,
If you go with the trend, pursuing Ph.D after M.Sc seems to be the most followed option. However, most of the IITs have great campus recruitment facilities for not only B.Tech students but also for other programmes such as M.Sc, M.Tech, integrated Ph.D, etc. For sure, you'll get a decent paying job.

Hi Sanjeev,
Until and unless you get your result, you cannot apply for M.Sc. Until and unless you have your marksheet and TC in your hand, no college will allow you to get admission. Hope this helps you. Best of luck!

You can work in a lab as an assistant for a factory or school. You can attempt government exams for various posts and vacancies. These are the only major jobs you can do. Although you won't get them easily.
