OP, reread your post.
Then reread the responses.
No, I wouldn’t like someone telling me that I was was bullying my kids, but if I wrote what you wrote, I would expect and deserve it. Punishing my children because they didn’t get 100% on a math test? Extreme and silly. As a person who worked in the local high school for 10 years, I would approach it this way: "WHere do you think your weakness was? Let’s work on that, and let’s talk to your teacher about how you problem-solved.

. Not true. Colleges tend to accept students who aren’t robots and know that no one is “perfect”; they will forgive a grade. That’s according to my husband’s alma mater: Stanford.
Punish your child for crashing a car, going drinking, arguing with a teacher, staying out past curfew, getting American tattooed. A number of parents are going through this and would be happy to have a dedicated child score well, and spend her summer trying to get into a major that they don’t like.
Punishing your child for being overweight and not getting 100% on a math test, speaks volumes.
