Prompt ambiguity, Scots Gaelic in 12 weeks

In the course “Scots Gaelic in 12 weeks” some of the prompts are ambigous. In level 4 I learned that “gu math” means “well.” Later in the same level I learned that “tha gu math” means “well.” When the English prompt is “well” I have no way to know if the expected response is “gu math” or “tha gu math.” It’s annoying to be given a poor score when I have typed in one of the TWO correct answers for a given prompt.

There is a second ambiguity in level 5. “Who are you? (familiar)” is the English prompt for both “Cò thu?” and “Cò thusa?”
