This lady is not very organized. She consistently schedules after school rehearsals and concerts for times that end up being something else. For rehearsals she tells parents that it's over at a certain time and then midway through the rehearsal, decides she's going to keep the students an hour or so later. Last Christmas, for their concert, she sent out announcements that had the incorrect start time so parents arrived over an hour early and had to sit there. Not good at all.
The class is great but, she should just not yell alot at all the students.
