During the Core test (Grammar, Reading, Listening), you filled all answers on the page and when you click Submit, it took a long time to submit and you have lost some time.
You probably experienced a temporary connectivity problem. Some short delays are already factored in the overall time limit but if you experienced a longer delay (total of 5min and more) and you failed the test, please let us know. We can check the impact of the issue on your overall result.
Please submit the support ticket with the details during which section (Grammar, Reading, Listening) it happened within 30 days from the test completion. We will check and if confirmed, you will be able to re-take the test.
