The 4-week classes are really helpful. Lukas provides the well organised outline before the class. The brainstorming and roleplay sections make me think about the issues from different perspective. It is a good practice to construct my idea orally.
Lukas is a friendly teacher who always creates a relaxed atmosphere in class.I really enjoyed the process from previewing the materials to discussing it thoroughly every week.It did help me to speak English more fluently.
