There are occasional issues that are apparently caused by the browser. For example, it may look like you haven’t answered the questions even if you have. The official grading system is independent of the scores displayed in your browser, so even if you encounter such problems, they will not affect your official results.

Try closing and opening your browser. Then, try logging in on a different browser or device.

We also recommend checking other FAQs here relating to missing certificate or answers appearing as incorrect/not submitted. Sometimes, a technical problem might turn out to be just a misunderstanding of the task or integral features of the platform (delay that might be caused by the peer-review process, for example).

If these steps don’t help, see if the Online Community already found an answer for the problem. You may also send the admins a private message about the issue in the community.

If you keep facing these technical issues, please send us a message.
