Learning Progress is a summary for a single student: homework status and attendance are visible for each lesson.
To view learning progress, open the Courses section, select a course, and the "Students" tab. Then, in the row for the desired student, open the "⋯" menu and select "Learning Progress." The modal displays a table of lessons, including homework grades (pass, assigned, or not assigned) and attendance status (present, remote, absent, and others). The administrator can manage attendance directly in the modal, and homework answers are checked on the "Homework Check" screen.
The summary is always opened for one student at a time - from the "Students" list.
