- very limited schedule of encounter class - size of chat & social class group is too large and the range of English skills is too wide: from beginner to advanced, so oftentimes I didn't learn about anything and it was not pleasurable to join - many topics & materials of social classes are too childish, not too suitable for people in my age - the material is way too easy for me. WSE should have provided a trial class. Also, I want to upgrade to business class by also cancelling this class but it was not allowed, yet when I ask for a refund, I need to wait for 9 months to prove that the program brings no improvement in my English skill - anyway, what does the "delivery" mean on below questions?
