The Add1Challenge is a 90-day challenge designed to take you from beginner level to conversational fluency. The end goal of the Add1Challenge is to have a 15-minute conversation with a native speaker, and it works! It has built-in daily accountability, a community of fellow challengers and well-crafted mini-challenges to push you to your goal. A new challenge starts every month! Highly recommended by the RhinoSpike co-founders!
