I'm not from America so what is eighth-grade?

Hi! Thanks for the question.

Eight grade in the US Educational System is categorized as middle
school or junior high (junior high school). Students in grade eight
are usually in the ages of 12 to 15 years old.

The following articles provide general overviews on the American
Educational System and will help you understand where eight grade
stand in your own country's educational system.

"Generally, school districts are divided into elementary schools,
middle schools or junior high schools, and high schools. Elementary
schools contain students in kindergarten and 1st through 5th or 6th
grades. Many children go to kindergarten when they are five years old.
Children begin first grade at age six."

"Depending on the school district, students follow elementary school
with either middle school or junior high school. Middle school
contains grades 6-8. Junior high school contains grades 7-9. Following
that, students go to high school. High school contains grades 9-12 or
10-12."
