Hii,Well Mainly Requiired to do MS in Germany are:

-Certificate and transcript of your undergraduate studies.

-Details of your secondary education –some very competitive application processes may wish to know further details of an international’s education history.

-Interviewing – German universities may discuss your application and your experience in an arranged interview with you. The interview may be formal, especially in highly-competitive universities with limited places, or it can also be done over conferencing platforms, like Skype to make it easier on international students.

-Additional entry tests –this more often occurs in competitive universities, where you may be asked to complete an additional entry exam or take a standardized postgraduate admission test as part of your application. This can also be required in law, medicine, and other similar regulated professions in order to ensure the compatibility of your previous trainings. Also, business schools and MBA programs may require a particular score from recognized tests, like GMAT or GRE.

Hope,this information helpful for you.Goodluck.
