Girls 16 years of age. I enjoy watching tests more than stage performance because we get to see girls [and boys] showing what they have learned and without adornment. This is such a good example for students taking timed academic tests. All the steps are timed, memorized, and executed. At about 8 mins, the light-haired girl in the front middle moves her head most masterfully, and if you focus on her head, you will lose yourself. Jumps at the end I could watch a thousand times. Pedagogue at end.
