To get to students who are enrolled in your course, go to: 'Courses' and select your course.
Inside your course, click the 'Students' tab.
You will be able to view all the students who are enrolled in that particular course. An advanced filter is automatically added, and you can also run reports.
Alternatively, you can access the 'Student' area via 'Site' > 'People' > 'Student'. Here, you can view all the students, and you can filter them based on the particular course using advanced filters.
It is more convenient to access the students directly from the course because the filtering is automatically supplied. However, if you want to view all the students in the system, you can use the 'Student' area.
