Fnd High school is the last segment of compulsory education in the United States (and Canada?).
In the United States, high school generally consists of grades 9, 10, 11 and 12, though this may vary slightly by school district. American students may leave high school at age 16 -18, depending on the State, which is usually grade 10 or 11 if the standard curriculum has been followed throughout life. So the last two years of high school are not compulsory, but most students complete their degree. A high school diploma or G.E.D. and a passing score on the SAT are generally required for entrance into a college or university.
(It may be parallel to British 'College'? (as opposed to 'University')?)
It is widely believed by persons age 14-34 that high school is the worst part of one's life, and widely beleived by persons age 35 and over that high school is the best part of one's life.

High school is the former name for secondary schools in Australia. The name was officially changed to secondary college in the early 1990s, but to the majority of the adult Australian population they are still remembered as high schools. The exact length of secondary school varies from state to state, but the majority teach Year 7-12. It is compulsory to attend school until the age of fifteen, but most students remain at school to complete their studies and go on to college or university.
