I found the level a bit too easy for a 3hour course,
but it fit what was in the learning objectives.
Very nice structure with the prerequisite page
and how to find the zoom url,
that was a nice way to do an exercise which could be used
for more aspects of the course.
Perhaps you could provide a bit more detail before moving on to the groups,
but I’m still happy with the course.
Overview could be presented in the form of a slide just at start.
But it is optional.
