Grades 10 through 12, often referred to as high school, typically encompass students aged 15 to 18. During these years, students take a variety of subjects, including mathematics, science, language arts, and social studies, which help prepare them for college or vocational training. In addition to core subjects, students may have the opportunity to explore electives such as art, music, or foreign languages. These grades also include important assessments like the SAT or ACT, which are often required for college admissions, and students may participate in extracurricular activities, including sports and clubs.
