If you're a parent, you might have seen some odd-looking letters written on your child's homework when it's been marked by a teacher. It turns out that there are some secret codes that teachers use.
Now, one teacher has explained what some of these mean. Miss Frankie, a teacher who's also become a TikTok star, posted a video on the platform looking at the subject.
She said that the codes are used between teachers. They include KCSIE, WWW and EBI, as well as various others, reports the Mirror.
