The English day its going to take place the 25th of the present month. It will be full of activities and the Hub will give a great instance for learning. To have an idea of what would you be able to do, imagine that it is a kind of science fair but in English.
In my opinion, this is an awesome event that should have taken place a lot of years before because it gives the opportunity for improving the most important language in the world and having fun at the same time.
