"Juniors" typically refers to students 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, such as the SAT or ACT, which are crucial for college admissions. This year is often considered a pivotal time for academic performance and planning for the future. In college, juniors are usually in their third year of a four-year degree program. They often focus on their major coursework and may begin internships or job shadowing to gain practical experience in their field. This stage is essential for building a resume and preparing for graduation and future employment opportunities.
