In order to get enrolled in a study program that is taught entirely in English, is it mandatory to have passed IELTS or TOEFL by the international students?
Yes, you need IELTS
or TOEFL to apply for a program at a German university that is entirely taught
in English. But in case, you already hold a Bachelors degree with English as
the medium of instruction and you’re applying for a postgraduate program, then
you may not need IELTS or TOEFL; however, these tests are strongly recommended
to ensure admission and successful visa.
