I can feel that Weng is a good teacher, though I could not understand what she said in the beginning. It could be because she was speaking too quickly or her voice was too low, so I didn't know which page we should start on. I couldn't follow her lesson until I figured it out by myself. I always have a problem in Callan Method lessons: if I don't see my textbook, I cannot follow the teacher's lesson. I don't know if it's the correct method of learning or a fault.
