So while I have a month off I am focusing on preparation and review. In America, review (復習-fukushuu) is a common study method, of course. But here in Japan, equally ubiquitous is yoshuu (予習) or studying ahead. At first it seemed kind of strange to study lessons I hadn't worked on with the teacher, but it's become a necessary tool. At the rate we study, the only way I can survive is to come into class with a fair idea of what we are going to work on. If I have any questions, I can ask, but during the class, we practice the pronunciation and usage. The rules, etc. I work on at home.
