I know nothing about this, but given the exceptional score you got it sounds like she was just jealous and wanted to bring you down any way she could. If you got the score you did you've already proven yourself, so I say
fuck her. Let her have her little rant; won't mean a thing after you graduate (do you graduate?)
Sounds to me like you're something of a prodigy. People always hate/fear prodigies. Probably jealous of your looks too. Don't let it get you down; YOU know you're good enough, and the numbers as ever don't lie.
Well done on your score!
