When you teach multiple students in different groups, it's important to be able to group students together in classes, for example, 'Beginners' or 'Monday Evening'.
Grouping students together into classes allows you to see only those students in your dashboard that belong to a specific class. And it makes it easy to assign homework to all students in one class but not in others.
To do that, Yousician recommends the use of tags. Simply edit your student's display name to include a tag like 'Beg' or 'MonEv' (short for 'Beginners' or 'Monday Evening') appended to their name. You will then have students displayed as 'Bruno - MonEv' or 'Oliver - Beg' in your dashboard.
You can then easily filter your dashboard for 'Beg' to show only students in the 'Beginner' class. And you can assign homework to all students in the 'Beg' class but nobody else with just a few clicks.
