Well, just let me say that no, the school does know my daughter well enough to know who would have copied. Last competition,last year (all multiple choice) my DD again got top 1%, and the other 4 all got credits, with almost same scores ( around 80 percentile ). The risk of my DD being accused of the cheating is almost zero. She is 3 years subject accelerated for math, whereas other kids only do one year ahead math curriculum. The identical written answers 3 of which were random as I said, and the fact they sat next to each other are proof enough that cheating occurred.
