While the Inspired Beginners series was first being published, we invited people to post the homework in our forums at our sister site Notes from Spain. Since then the forum has closed, as we concentrate our time more on making new materials for Notes in Spanish and other new projects, so I'm sorry that it isn't possible any longer to post homework there.
However, we really recommend you still have a go at the homework in a notebook. Even if you have no one to check it, the simple act of looking up new vocab and using it in writing is a huge boost for your Spanish!
