Somehow there is not enough interactivity around speaking and listening. Some activities are writing, some speaking, the quiz environments largely test grammar but language is whole and you can't take time figuring out what you are going to say.

Hi Mike, thank you for your review. We're pretty big on speaking so make sure you're interacting with the voice recognition whenever you can. You'll find plenty of opportunities to use it in your lessons as well as in the Rocket reinforcement activities. All the best!
