I think it is not a good idea to put all people on the waiting list. If they really have no chance - should inform the parent the reality instead of keeping people's hope there. Don't understand why this school do it this way!?
we are in the same situation - pm waiting and my son answers all the questions correctly and he was extremely co-operative on the interview day (push chair, say good morning and goodbye etc). Really don't know what has gone wrong. The only thing I can think of is he is not in their nursery class this year.
