unable to advance to next topic
I have finished up to time and no other topics are highlighted
what are you referring to by "stage 3"?
Also, did you read the Support Pages and the other discussions linked in previous messages and which explain what you have to do to access next lessons?
Currently, you didn't complete all the lessons of the Skill "Basics 2". As long as you'll not have complete all the lessons of that skill (and of the skill "Phrases"), you'll not have access to the next line of skills ("Food" and "Animals"), see the links provided for explanations.
