There are two types of deadline handling for an assignment, Soft and Hard. New assignments have soft as a default.
To change the deadline handling for an assignment, follow the Edit deadline handling-link from the assignment dashboard.
Students can upload deliveries and add comments after deadline expiration. Deliveries made after the deadline will be clearly highlighted and examiners might not take these deliveries into consideration when correcting deliveries.
