The structure of the digital TestDaF makes some mistakes permanent: you cannot return to earlier tasks in any section, each Speaking task has a fixed speaking time, and Writing has clear word targets. The mistakes below are based on the TestDaF-Institut’s official structure information.
General mistakes
- Leaving a task half-done to “come back later”: there is no going back in the digital exam.
- Rushing tasks you suspect are trial items: you cannot know which ones don’t count.
- Seeing the platform for the first time on exam day: official tutorials and sample tasks are free.
- Starting Reading without splitting its roughly 55 minutes across the tasks.
Writing mistakes
| Mistake | Effect | Fix |
|---|---|---|
| Under 200 words in the argumentative text | Task requirement not met | 5 minutes planning, write, check word count at the end |
| Skipping the counter-argument | Weak argumentation | Give one paragraph to the counter-view and rebuttal |
| Adding your opinion to the graph summary | The task is to summarise, not comment | Compare text and graph data |
| Misreporting figures from the graph | Content error | Check units and years one by one |
Speaking and Listening mistakes
- A long opening in the 45-second “Rat geben” task, leaving no time for the advice.
- Speaking without structure in “Thema präsentieren” (2:30) and finishing early.
- Replacing the summary with your own opinion in “Text zusammenfassen”.
- Writing unnecessarily long answers in short-answer listening tasks and running out of time.
