The census date is the final day on which students can withdraw from a unit and receive a refund of tuition fees, and have the unit removed from their academic transcripts. Students who withdraw from a unit after the census date for that unit will not receive a refund of fees and will have the unit recorded on their academic transcript. The census dates for standard 12-week semester-length units are listed in the key dates for the academic year. Every unit is assigned a census date.
