Thank you.
That's what my husband (PhD in science field) says. He says that the score is the dependent variable and the intelligence or knowledge is the independent variable and to get the high scoes one must think what confounding factors could impact the test to yield a high score. Really cheating is not possible as the child had a 1:1 proctor, unless the proctor cheated. My son said she didn't speak to him the entire time.
The test is a very robust test. So one would assume the chance of guessing that many right would be phenomenally low.
However, lots of confounding variables can bring about low scores...distractibilty, physical disability, temperature of room, noise, boredom...it is endless.
