A "Senior Student" typically refers to a student in their final year of high school or college. In high school, seniors are usually in the 12th grade, while in college, they are in their fourth year of study. This stage is crucial as students prepare for graduation and transition to the next phase of their education or career. Senior students often take advanced courses and may participate in activities such as college applications, internships, or senior projects. They may also engage in leadership roles within student organizations and participate in events like graduation ceremonies to celebrate their achievements.
