Senior year is the final year of high school, typically for students aged 17 to 18. It is a significant time for students as they prepare for graduation and transition to adulthood. During this year, students often take advanced courses, participate in extracurricular activities, and focus on college applications or career plans. In addition to academics, senior year includes important events such as prom, senior trips, and graduation ceremonies. Students also receive their diplomas at the end of the year, marking the completion of their high school education and the beginning of new opportunities in higher education or the workforce.
