B.Tech Scope

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.

Yes. you can do it. Definitely, it is a good choice if you have interest in it. It will not affect but enhance your job prospects if you develop relevant skills.

There is huge scope in this field. In past 2-3 years the competition has raised to a tremendous level and your success depends on your interests in coding and the college you get through JEE. You future work completely depends on computer.

You will not face problems in admission for BTech in a majority of engineering colleges if you drop two years.
