I have finished a unit but in My Progress it does not appear as completed.

To complete a unit you need to have 100% progress and a score of 50% or more in the Self Check. To complete a Skills Practice or World English unit you need to have 100% progress. If you do not have 100% in the Progress bar it means that you did not finish one of the pages in the unit. Click on the + button to check which page you did not finish.
