I actually had this happen back in high school. The teacher gave us “anonymous” surveys to gauge her performance. She analyzed the handwriting to determine which one was mine. I actively tried to change my handwriting as well, but I guess not well enough. I’ve never trusted a survey was actually anonymous after that.

The same thing happened to a friend of mind in junior highschool. The teacher even called him out in front of the whole class for giving her bad ratings. We all did, but she recognized his handwriting in particular:-D
