You can prove that you have completed the training either by confirming that you have completed the training after watching all the videos or by passing a test at the end of the training. The method of confirmation of completion of training depends on whether there is an test at the end of the training or not.
You can find the completed trainings in the drop-down menu in the upper right corner of the page, which you can open by clicking on your name. The same information can also be found on the left side of the page under the Profile icon. Click Completed studies from the menu.
To view the certificate of completion for each training, click the light green certificate icon at the top of the training. Your certificate will open in a new tab.
You can also filter to show only specific activities of yours. After the filtering section, you can see an overall picture of your attainments, i.e. the number of completed studies and the total duration. You can also download a register of all your activities by clicking the Activity register icon.
