A Junior Student typically refers to a student in their third year of high school or college. In high school, juniors are usually around 16 to 17 years old and are preparing for important exams like the SAT or ACT. In college, junior students are often focused on their major and may start taking more specialized courses related to their field of study. During this year, junior students often participate in extracurricular activities, such as sports or clubs, which can enhance their college applications. They may also begin exploring potential career paths and internships, gaining valuable experience that can help them after graduation.
