B.Tech Scope

DTU has one of the best placement record after legacy IITs. If you study well, you will definitely get placed in a good company.

Yes sure, no problem in that. But, there are more options, like you can be at the different food directories and food manager in hotels and restaurants.

Hi,
1. B.Tech (CS) has a lot of subjects, if you see all the four years course structure.
2. It also varies college-to-college.
3. If you could tell us which college or university are you considering?

No, you can't get admission here. You should at least have 65% marks in boards to get admission. Try to fill improvement form and improve your marks, then take admission in any institute. It will be beneficial for you.

Hello Rahul! Go for M. Tech if you're more inclined towards the technical field and wish to make a career in it. Else you can opt for MBA if you're interested in the management field. Both options are equally rewarding, only if these degrees are pursued from reputed colleges.

Obviously u need to do M.Tech not MBA. As, through MBA, you will lead in managerial line which does not suit you. But, you also have to complete your Ph.D in respective field to be a complete 'research scientist'. So, my answer is a big 'No' to MBA, although you have to go for M.Tech.
Best of Luck.
