This.
However, at my high school it really isn’t a free for all. Teachers make recommendations on placement level for next course in sequence and separately, students make their requests. Counselors meet with each student and they discuss courses that the student asked for something different than the teacher. Student doesn’t always get their choice. There’s still a lot of changes anyway at the start of the year when kids realize they aren’t ready for a higher level course or are willing g to put in the time needed.
