Hi Vaibhav,

German universities are among some of the top for undergraduate programs. The admission process for the courses are is very competitive. 

For UG programs in German universities, foreign candidates should have completed a Germany approved higher educational with satisfactory GPA.

I suggest you to check your qualifications with German Academic Exchange Service (DAAD) https://www.daad.de/deutschland/nach-deutschland/voraussetzungen/en/57293-daad-database-on-admission-requirements/

You may also be required to appear for JEE to facilitate your admission process. Also, you are required to know German as most undergraduate programs are in the German language.

Do revert if you need more information.
