First, I do not care the one test. Because many super genius also can make mistake.
My daughter was rejected twice. However, when she was in middle school, she in advance class and entire class got straight A and got presidential award.
Now, tell your daughter, smart student needs to learn how to fall down and success from there. As Chinese said, fall down is the mother of success.
The test result is not important because some questions may be out your daughter study area. She needs learn a lot of more to stand over all next two years level. Another word, high schooler easy to solve middle school question. Elementary math question is too easy for middle schooler. Need to study a lot of more in the goal.
