An AI marker will hunt for a mistake that is not there
Give a grading model a list of "common misconceptions" and one of them is wrong, and it will find that error in a child's work anyway — then take marks off for it.
Why students need AI coaches, not AI answers
Show the answer on a wrong attempt and allow unlimited retries, and the score you record stops measuring understanding. It measures persistence.

We fact-checked a stratified sample of our own primers. Grade 8 carried real errors; grades 1, 3 and 6 carried none. The harder the content, the thinner the model gets.
