Reporting a bug
It helps to tell us which page you were on, what you expected to happen and what happened instead. If a result looks wrong, include the test, age, gender and score you entered.
Please do not send student files or real student names. The tool works without uploading anything, and we do not need personal data to look into a problem. Made-up example values are enough.
