Go to your Canvas Account or to the Student Portal. ALL information is updated hourly: 24 hours/day, 7 days/ week, so information is very accurate. If your student completes any work, it will be reflected within an hour on the Student Portal and on your Canvas account. All due dates for the entire class as well as scores for completed work can be viewed by selecting the "progress report" option.
The software that students use is called Apex, and may or may not also show dates and scores. These dates and scores are NOT accurate, as CUSD weights all exams and sets dates so that no work is never due on weekends or school holidays.
ALWAYS use Canvas or the Student Portal ONLY for due date and grade information.
