Group lessons usually have 4 students, but sometimes this is less. They are organised so that all students are of the same level, so that they can make great progress together. The group lessons are usually 1 hour long.
In these lessons you can interact in real-time with other learners from all around the world, which can be a very rewarding experience. All students are made to feel at ease in the class and will feel coonfident to contribute to discussions.
