Hi Govind,
Please go through the DAAD website and check the list of funding opportunities they have. 100% scholarship is possible but seem to be a little difficult for you basis 70%. Instead of simply relying on a scholarship you should also think of applying for an education loan. More than half of the student population in India takes an education loan to study abroad so why can't you? Keep looking for options and something or the other will work out. Scholarships are always on the basis of merit, ability, skills etc.

Hello Nitish,
It's good to dream and dream big. Yes, it's a good idea to do graduation in Germany. Be advised that academic standards there are of very high order. I hope you have this in your 10th / 12th.
I would advise you to approach a specialist agency dealing with sending students to Germany. This is because there are many nuances and you should know all of them.
