The TestDaF is the standard language exam for studying in Germany and is held worldwide on fixed dates. It is graded from TDN 3 to TDN 5, and most degree programmes require TDN 4 in all four sections.
In Munich, language schools offer both morning intensive courses and evening classes, often with an exam centre attached.
There is nothing currently scheduled for TestDaF in München. The language schools here still take enquiries.
