The UH academic calendar clusters four major deadline periods: registration, add/drop, withdrawal, and grade submission. Registration opens in early August, with a firm deadline two weeks later. Add/drop runs for the first two weeks of the semester, after which courses are locked in. Withdrawal deadlines appear midway through the term, and final grades must be posted within ten days of the last class session.
Each deadline serves a purpose: registration secures enrollment numbers, add/drop lets students fine‑tune schedules, withdrawal protects GPA, and grade posting ensures transcript accuracy. Yet the same structure can strain students juggling work, health, or unexpected life events. Knowing the exact dates and the reasoning behind them helps you anticipate pressure points before they become problems.
