English Students’ Education

English schools begin in September after a long summer holiday. There are two terms in a school year. The first term is from September to January, and the second term is from February to June. Most English children begin to go to school when they are five years old. When they finish high school, they are seventeen or eighteen years old.

High school students take only five or six subjects each term. They usually go the the same class every day, and they have homework for every class. After class, they do a lot of interesting things. After high school, many students go to college^①. They usually have to pay a lot of money. So they have to work after class to get money for their studies.
