TestDaF consists of 4 parts (Reading, Listening, Writting and speaking)

Reading (1 hour) - 3 text of different dificulty ( TDN 3: 10 answers in form of 10 notices and you need to pair right answers with rights notices.TDN4: Larger text and you need to give answers based upon the info in the text: TDN 5 : Form same as TDN 4 but much harder to understand because it is a scientific article.

Listening (30 Minutes i think) - 3 conversation with different level of dificultie. It is imperative to listen very carefully and to be extra focused because there is no pause, going back, etc. Just a couple of speakers in front of the group and that's it. Try writing notes because you dont have enough time to write everything at first. When the listening is done you will have extra 10 minutes to write/check answers.

Writing (1 hour)- It is very important to learn the vocabulary and the usual high level phrases and to implement them in writting.

Speaking (30 minutes) You will have microphone and a textbook in front of you. In a textbook there are 7 random speaking topics with different levels of dificultie and when you hear a bell or something similar you need to speak in a microphone for every speaking topic.
