Munich

Your class 12th percentage must be above 75%. In Germany, universities ask for 13 years of education but in India, we have 12 years of studying experience. So you have three options:
1. Clear IIT-JEE Main and Advanced
2. Spend a year at a university in India
3. Do Studienkolleg
After that, you need to pass TestDaf up to level c2 to prove your knowledge of the German language. The chances depend on your marks. You can apply via university assist.

You must score more than 75% in your 12th board, but getting good grades boosts your application.

Hello Rahul,
Check this and also email them personally to ask them for student placement:

It will be worth to study business in any international business schools. Munich has the best business school. Any higher study done in Germany has its worth since it offers the best education.

If that is what you want to do then you should know how good or bad and how beneficial it is for you. It might fetch you a job but clearly it is your decision to make whether to study or not keeping in mind what you expect out of it.
