Why do most seniors often earn lower grades in their last semester before graduation?

Most seniors often earn lower grades in their last semester due to a combination of factors such as senioritis, a decline in motivation as they approach graduation, and the increased focus on post-graduation plans like job searching or applications for further education. Additionally, the pressure of completing final projects and exams can lead to stress and burnout, impacting their academic performance. Furthermore, many students may prioritize enjoying their final experiences in college over academic commitments.
