How has Paul's academic behavior changed at the beginning of the new school year?

Paul's academic behavior at the beginning of the new school year has shifted in a negative direction by associating with a problem-causing peer group. This change is significant as it suggests that he may be influenced by those around him, which can lead to distractions from his studies, potentially affecting his motivation and focus. This association often results in less engagement with academic responsibilities, as peers who yield negative influences can divert one's attention from positive academic pursuits. Understanding how peer relationships impact student behavior is critical as they can drastically alter a student's academic trajectory, leading to potential declines in performance and a shift in priorities away from academics.
