While I am so glad it was simply an entry error with respect to the grade, please keep an eye on this class and how things are going. The nickname is concerning and it sounds like there are a few other "yellow flags" with this class. Just keep an eye on how your child is reacting to the class. Push her a little for information if she seems upset about what is going on. Make sure she KNOWS you have her back, will help if she needs support or for you to intervene and trust everything she tells you.

You want to get ahead of any issues so they do not spiral. Good work to you and your DC!!!
