Do you know what American students have to do in their schools? In America, at the beginning of the term, students must choose their courses and teachers first. While in China students usually have no chances to choose their courses and teachers.

Choosing is very important for your grades in America. So at the first term, don’t choose too many courses, or you’ll feel very nervous and it may influence your study. Then you have to ask for some teaching plans. There is some information about subjects, time arranging, marks and textbooks. At the same time, you must choose the teachers. Different teachers have different teaching methods. If the teacher is called “killer” by the last grade, many students will give up choosing him. Because this kind of teacher will leave too much homework, too many exams and give too low grades.

There is another thing after you choose the courses and the teachers. How to buy textbooks makes each student feel hard. The textbooks in America are very expensive. Each copy is about $30～$50. In order to save money, many students buy some used textbooks, and some students usually borrow textbooks from the school library. You must get enough ready before classes. In class, discussing is very important. The teacher encourages you to raise questions or show your own opinions. They don’t usually ask you to sit well. Instead they allow you to sit or stand everywhere you like. They don’t give you much homework to do. You can learn some knowledge and do exercises by yourself.
