Пожалуйста помогите! Say what you do in class, before and after classes. Дам 20 баллов!

Before the classes I usually talk to my classmates. We are discussing something interesting and laughing. When we are in class everybody is busy with their own tasks. Were reading, writing something down, listening to the teacher, repeating and translating. After the classes we are waiting for our homework to be given and everyone is going home. On the way home were also having fun and telling each other funny jokes.
