How does i2istudy make revenues?

The project is bases on the model of freemium which is one of the free functions provided while premium features are available in a subscription. We charge money from those who prefer only to learn, but do not want to teach, as well as a percentage commission with teachers, who want to teach only for the money and are not necessarily interested in learning themselves. However, the time-bank study model (the mutual learning of a foreign language, which has a cost structure based in minutes) remains free and will always be free!
