we are not taking our spot, and the pp is right - last year was such a disaster that they went all the way through the wait list and then had to start accepting people they hadn't even interviewed. Given that they have an absentee principal who does not seem to care if they survive, I would not be surprised if he did not bother to fix the problem.
At #13, you have absolutely nothing to worry about. Tell your child that everything is going to be ok.
Congratulations! I would say with confidence that on May 1 your child will be accepted to Walls!
