I am glad to hear of you again. You want to know that everything is going in our school. In shortly, all has been improving since the school had began to carry on new policies. In the past, teachers always keep on explaining the points in class. Our students just listened and took note. But now we often discuss and try to solve the problems raising by the teachers or ourselves. Before class, we enjoy different kinds of activities instead of doing endless homework. For example, we can read what we are interested in. We can go to the library or surf Internet for various kinds of information. We are now masters of study, and we are happy.
