What does anybody make of this? (Vanity)

Me

This afternoon I logged on to my daughter's college account and found out grades had come out. I was very excited to see that she had received a 3.75 and was very happy for her. I showed her and the entire family and we went out to celebrate (dinner). I shared my happiness via Facebook. Tonight I went back on to pay a fee that I had noticed earlier was yet unpaid and her grades are completely different! She has one A, a B, two C's and a D! I don't have any clue how this is possible. One of her classes-- which is now a B-- she was given an award for best academic paper and that was her final grade. All other tests in that class were A's. What's going on? I can't contact the school until Monday, do you think it's hacking? I know this probably sounds like a joke but it's not.

Everyday.

1) My daughter does take care of her own things. I was on her account because I was paying. She didn't care that I looked at grades, because I am always proud of her grades.
2) Daughter wished she had screen capped grades too, but then she remembered today she texted a copy of the 3.75 gpa page to a friend. The two are very competitive. She erased her text but friend still had her copy. We now have that. Daughter is calling school Monday.
3) It seems a lot of work is going on with the school website this weekend. Many things have been changed and updated. I don't know if it's all some weird mistake.
