How do I contact the support team in case of difficulties during the exam?

To contact the invigilator, you must use the integrated chat widget that appears in the bottom right-hand corner of the screen once you are in the lockdown environment. Do not close the chat before you have received an answer, you can minimise the window with "-".

The invigilator can also contact you via the chat widget.

The chat widget is present in the first tab (editor tab) and remains active when you are on another tab.

If you cannot enter the flow and the chat widget is not available and only in an emergency case please call +49 89 2399 5155.

Communication via email will not be dealt with.
