If you want to live there and work there after your study and want to make connections then my suggestion is to learn at least German A2 level from Goethe. It will also help you to get
admission there. After you get admission, you will be offered to learn German language in your semesters without any fees.
All the best.
Note: Always opt for Goethe institute to learn German language as the embassy only recognize its certificate.

Yes, but you've to search for the institutes which offers the concern subjects.

Dear Yashika,
If you love playing with numbers consider pursuing a degree in accounting, finance, economics or business. You must research well on the program structure and see what interests you the most. Some of the best universities you can consider abroad are London School of Economics and Political Science (LSE),
London Business School, New York University (NYU), National University of Singapore (NUS),Princeton University, Imperial College London to name a few.
I am not aware about Indian universities on the whole.
