Due to the size of the groups (10 participants max.) and the length of the sessions (1 hour), I preferred to divide the four main skills (reading, listening, writing, and speaking) into two groups. I noticed that some people prefer to continue working on their comprehension (even at a B1/B2 level) and others want to increase their fluency when speaking/writing and reduce their mistakes. There are still those who would like to work on all the skills at the same time. They are invited to join both groups 🙂 .
