There is no excuse for not doing yourassignments . If you can't come to school, you should call your teacher or your classmate and ask about homework. It is yourresponsibility to find out what homework you have missed. It is not the teacher's job to remind you of the missed assignments. You must not be absent on a test day. If you are seriously ill, call and let the teacher know you will not be there for the test. If your teacher allows amake-up test ,you should take the test within one or two days after you return to class. Serious illness is the only reason for missing a test. Be on time! It is impolite to be late. Also, it bothers other students. If you must come in late, be sure to do it quietly. Have your books and papers out of your bag before you come into the room. Then go to your seat and sit down quietly. In the USA, it is not necessary to knock before you enter the classroom. Most teachers will give you a low grade if you are often late. In America, you should call your teacher by his or her last name instead of " teacher". Also you should use Mr, Miss, Ms or Mrs before the last name ( such as Mrs Smith or Mr Jones). This is polite. The teacher will tell you the title that he or she likes. It is impolite in the USA to eat, drink or chew gum during class. Don't do these until the break. Also, removing your shoes in the classroom is not polite. When can a student miss a test according to the passage?
