    Life in an American high school is an interesting and exciting learning experience. High school in America is not just a place for studying some subjects. It is also an important social centre, where students can develop other interests and talents.

The high school course is divided into four years. The teenager usually starts school about 8:00 a.m, and ends at 3 p.m. There is no school on weekends. Students have lunch at the school cafeteria. After lunch they play sports, talk to friends or simply relax. The lunch break lasts about an hour.

When the school day ends, some students go home, but many still stay at school for after-school activities. There are many activities and clubs to choose. In the afternoon many students practise sports with the school students team. Sports are an important part of high school life. American high school students like to be “popular”. This means being a good student, being active in the community and being well-liked by others. Most American high school students have part-time job during the school year and a full-job during the summer. Parents encourage their children to work because it's part of growing up and becoming responsible and independent. Most high schools have a job list to help students find work. Teenagers are fond of their jobs!
