Here you will find a model test with the corresponding test key. This test is similar to the qualification exam in length and complexity.
I recommend you to proceed with the model test as follows:
- Settle yourself in a "realistic examination atmosphere". See to a quiet work place and take the real examination time of 90 minutes as your timeline.
- Work through the model test, but do not betray yourself: Do not use any other resources for solving the test than the ones which will be allowed during the real examination.
- Do not use the test key when solving the test! First, finish the model test completely on your own devices, and after that check your answers with the key.
This will help you to find out in which topics you will still need some more practise for the exam.
