USC revises its class schedule each semester to balance faculty workloads, room availability, and enrollment trends. For seniors, those adjustments can alter when required courses meet, the number of sections offered, and the sequence in which electives become available. Knowing the mechanics helps you anticipate where a change might intersect with your personal plan and prevents surprises late in the semester.
Because senior-year requirements are time‑sensitive, a shift in class timing can ripple through your graduation pathway. A course that moved from a fall to a spring offering might mean you need to retake a prerequisite or adjust an independent study. Understanding the ripple effect early lets you act before enrollment deadlines close, keeping your degree progress on track.
