Events are currently free webinars, meetings or gatherings organised by the 5StarTeacher team to teach you something. It's usually for training or teaching. For example, it can be for teaching English for a specific subject to a specific audience but sometimes it can also be just to engage with students or teachers or members of the 5StarTeacher team. Join them whenever you can if you have the correct requirements to join.
