there must be a mistake…

I am the treasurer of the Debate team. I’m in student council, Leo’s club, and choir. I am on the cheerleading squad. I am in the National Honor Society. I’ve taken the most difficult classes I could possibly take ever since preschool. I am ranked 13th out of
289(?) people in my senior class and I have a 3.9 GPA. 

So can someone please explain to me how on earth I managed to get myself on academic probation???

There must be a mistake…. :-/
