The first thing you need to know is that before you study in Germany, you are required to have a Hochschulzugangsberechtigung (HZB), meaning ‘higher education entrance qualification’.
Once you have that, find out if your qualifications are accepted by the German university you want to apply to.
Conduct extensive research and find a program and a university that best suits your scores as well as preferences.
Then, check the university language requirements.
Submit your scores of tests such as GRE, GMAT, IELTS /TOEFL, etc. along with your past educations scores and the relevant documents.
Now, all you need to do is submit your application and wait for the results.
