International English Language Testing System (IELTS)
It is likely that you need to prove your English language proficiency in order to apply for a Masters course in Germany. You can prove it by taking a test. TOEFL and IELTS are two widely accepted international standardized English language tests. If you are also planning to apply to few of the US universities, TOEFL could be a better choice. Whereas, IELTS test score is accepted by almost all the German universities. Both the tests have the same sections and similar testing styles. But in my opinion, IELTS is simpler and better option.
