“Lecture attendance”
Recorded lectures are favourite

At what time do students “attend” recorded lectures ?
Lorem ipsum dolor sit amet, consectetuer adipiscing
Cras vestibulum ipsum in lorem.
Aliquam libero magna
Eget fermentum quis rutrum eu erat.
Suspendisse tempus dui ut eros.
Aenean pulvinar eleifend ipsum.
Recorded lecture are viewed live, or on demand the same day,
or a week later, but mostly on the day(s) direct before the exam
