Schools in the USA are a little different from schools in Vietnam. Usually, there is no school uniform. Classes start at 8:30 each morning and the school day ends at 3:30 or 4 o’clock. There are no lessons on Saturday. Students have one hour for lunch and two 20-minute breaks each day. One break is in the morning, the other is in the afternoon. Students often go to the school cafeteria and buy snacks and drinks at a break or at lunchtime. The most popular after-school activities are baseball, football and basketball.
