Freshman, sophomore, junior, senior

In the United States, high schools and universities are typically four-year experiences, from ages 14 to age 18 (high school) and from ages 18 to 22 (university). Each of the four years has a name. The first year is called the freshman year, the second year is the sophomore year, followed by the junior and senior years. A 14-year-old is a freshman in high school; a 19 year-old is often a sophomore in college (university).
