Corrections and missing products
If a product is described wrong, priced wrong, or missing from a category, include the category, the product, and a link to the source. Fixes change grades for everyone, so we check sources before we change anything.
Disagreeing with a grade
A grade is the output of the answers plus the published rules, so the useful note points at the rule. Read how the grade is made, then share the quiz link from your address bar. That link carries every answer, so we can reproduce what you saw.
For agents and automations
You do not need to contact us to pull data. The grader is a public API with no key. See for agents.
