My DD10 started 6th grade having skipped 5th. The first full day she came home freaking out because she didn't finish her math in the math period for the first time ever and it was easy math. She asked me "What's going to happen if I don't get straight A's? What if I get a B? How will I get the harder work done if I couldn't get the easy stuff done?" with a look of terror on her face. I told her "The sun will explode, the universe will be destroyed and because of you humanity is toast." She gave me "The Look." Fortunately, for all of us, the last two days her work was done within the time period.
