wrote a note to ap test grader

took my calc ab exam and didnt know what to do on one part of an frq so i wrote "thank you AP grader ♡" in the bottom right corner inside the box. sent a request to the college board asking if this would get my score invalidated and they couldnt tell me.

of course i meant it kindly but im freaking out. i didnt write any information about myself, nor did i do anything to jeopardize my score beyond that.

could i be screwed?

edit: thank you all so much for your reassuring words and funny stories, i appreciate you! <3
