How completion works
Pass the practice question in every lesson first, then pass four assessment sets in order. Each set has 10 distinct questions and requires at least 80% (8 out of 10). All four must be passed; a high score in one cannot compensate for another. It is open-book and must be your own work. This automated assessment checks course understanding; it does not independently verify identity or workplace competence.
Each set attempt has its own 15-minute window. Starting an attempt counts even if you abandon it. Wait 15 minutes from the start before a retake; after every third attempt of the same set wait 24 hours. Passed sets stay saved. A live attempt can be resumed. Retakes and learning remain free.
