In the context of education, "juniors" typically refer 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. They often take advanced courses to strengthen their academic profiles. In college, juniors are students who have completed two years of study and are usually around 20 to 21 years old. They often focus on their major subjects and may begin internships or research projects to gain practical experience in their field. This year is significant for planning future career paths or graduate studies.
