The mixed course: sometimes online, sometimes face-to-face; the group decides
The course takes place every week at the same time, for example, on Tuesdays at 5pm. The difference with the face-to-face courses or the pure courses by videoconference is that, in this modality, the group decides if they are in the language school or by zoom.
The advantage of this combination of face-to-face and videoconference courses is that students do not miss any classes.
If, for example, the teacher is in Spain the class will be given online, or if anyone on the course is too sick to go out but is well enough to attend class. The group agrees in advance with the teacher.
