She wrote a strong password in her computers exam, then scratched it out so the teacher wouldn't see it

Class 5 half-yearly. Question 4: write an example of a strong password. She wrote a good one, she says. Then she crossed it out so hard the paper tore, because 'now the teacher knows it'. Got 1 out of 2, with 'example only' written next to it. I work in security. I've never been prouder of a lost mark 🤷
