These days, I'm taking The Full Book Revision from Stage 1 to 4.There are no explanations during the revision, so I have to answer the questions the teacher asks me quickly all the time during the lesson, and I feel a bit tired. But I found that the teacher is working harder than me because they have to constantly ask questions and pay attention to my answers. Even in such a situation, she gave me an enjoyable lesson with her enthusiasm. I appreciate her very much.
