I.m sorry that you had such a disappointing experience. But don.t be too depressed about it. The children misbehaved. But you were dealing with this not just ignoring it. The observer may have actually meant that it WAS interesting to see your sytrategies in this situation. The final decision may rest on wht other candidates achieved. Don.t forget tha it is a competition. But don.t give up hope either. Good luck.
