The German citizenship test contains 33 questions. Thirty are general questions and three are state-specific. You have 60 minutes to complete the exam.
You pass with at least 17 correct answers. A realistic simulation should mirror exactly this structure.
Do not use simulation as your very first step. It becomes most useful once you already know the questions from practice mode and want to test how stable your knowledge is under exam conditions.
That gives you a more honest picture of how prepared you really are.
The final score is not the only thing that matters. Pay attention to where you felt uncertain and which questions you guessed correctly without real confidence.
After that, return to practice mode and review those weak spots directly.
