Well, choosing specialisation depends on your interest and career goals. The common requirements to study Masters in Germany are:-
1. Bachelors degree with good CGPA (3.5 or above).
2. Proof of language -In Germany, most of the universities provide Masters in the German language if you want to study in German, then you need to take TestDaf or DSH test or for international students, there are few universities which provide Masters in English. As you are from India, you need to take IELTS or TOEFL for English language proof. University entrance test like GMAT/GRE (if required). Health Insurance
Student Visa
Other Certificates. Entry requirements for university admission vary from university to university.
