"Users must be able to use the history and the ""Mark complete"" button offline and online while working on courses. Please implement that the history and the ""Mark complete"" button are available offline and that the history is automatically synchronized when users switch back from offline to online. Users should not have to deal with syncing history. Taking a course should be as easy offline as it is online.
