• It’s an “X” to indicate incorrect answer. The teacher has 100+ papers to grade and a lesson plan to get together for tomorrow and doesn’t have time to make their marks look pretty.

        I’m in a different pink collar profession and sometimes when I have an audit checklist to circle “yes” for “I did the thing” down 15 items my circles just turn into a long chained spiral.

      I used to have a teacher (and multiple others since then) back in the 90s who also used the same squiggly to indicate correct answers. Not sure what the origin is, but I’ve also used it since

        That’s interesting. I had the exact opposite experience in the same timeframe. Those are X’s written really fast and the pen doesn’t leave the page. I’ve only ever seen those marks used to indicate incorrect answers.

          Now that I think about it, maybe the “correct” ones were rotated 90 degrees counter-clockwise, in which case I guess it might mean a quickly drawn V?

            Yeah when I was in school it was X for wrong (with the loop as pictured) and check marks for correct. And a check mark can certainly look like a V when going fast. ✔️

      In addition to what others have said (this is an X), American teachers traditionally use red pen to mark incorrect answers/correct mistakes.

      The teacher marked these as incorrect.
