What helps me help you

• What you expected and what happened instead.
• The question, if it is about a question — its wording is enough to find it.
• Your device and iOS version.

A question looks wrong

Tell me which one. Questions are generated from catalogs, so a wrong question is usually a wrong rule rather than a typo — and fixing the rule fixes every question like it. That is worth more than one correction, so these reports are the most useful ones I get.

Why there is no reading or listening section

Because I have no material for either, and a section built from nothing would measure nothing. The app says this on its opening screen, before you start, rather than in the small print afterwards.

Why the test does not tell you if an answer was right

Because seeing three mistakes in a row changes how you answer the fourth. The result would then describe your nerve rather than your Japanese. The result comes at the end.
