There are two terms in a school year in America. The first is from September to January, and the second is from February to June.
American children usually begin to go to school at the age of five. Most students are 17 or 18 years old when they finish high school. High school students have only four or five subjects each term. They usually go to the same class every day, and they have homework for each class. After class they do many interesting things.
After high school, many students go to college. They usually have to pay a lot of money. So many college students work after class to get the money for their studies.
