The senior cycle refers to the final stage of secondary education, typically for students aged 16 to 18. In many countries, this phase prepares students for higher education or vocational training. It often includes a range of subjects, allowing students to specialize in areas of interest while also fulfilling core curriculum requirements. In Ireland, the senior cycle culminates in the Leaving Certificate examination, which is crucial for university admission. Students can choose from various subjects, including mathematics, science, and languages, and they often engage in projects or practical assessments to demonstrate their skills and knowledge.
