Upper secondary school is an educational stage that typically follows lower secondary school and is designed for students aged around 16 to 19 years. It usually lasts for two to three years and prepares students for higher education, vocational training, or entering the workforce. In many countries, upper secondary school offers a variety of subjects, allowing students to specialize in areas such as sciences, humanities, or arts. Students often take exams at the end of this stage, which can influence their future educational and career opportunities.
