Replace a broad complaint with an observable event
Describe a sentence you could not understand or an answer you chose incorrectly. Explain what you thought the clue meant. This gives Mocchi a concrete starting point and makes it easier to distinguish a missing word from a misunderstood relationship. 'Particles are difficult' names a subject; 'I use a destination particle for an action location' identifies a decision you can test.
Keep the target connected to your goal. A repeated issue in messages you need to read may deserve attention before a rare expression you encountered once. Personalization should help you choose useful priorities rather than turn every possible mistake into an equally urgent lesson.
Use a contrast that reveals the missing clue
If the problem concerns where an activity happens, compare a simple action-location sentence with a destination sentence. Explain why the place has a different role. Ask Mocchi to vary the activity and location after the first pair so the review tests the relationship instead of familiarity with one corrected line.

| Japanese | Romaji | Meaning |
|---|---|---|
| 店で買い物をします。 | Mise de kaimono o shimasu. | I shop at the store. |
| 店に行きます。 | Mise ni ikimasu. | I go to the store. |
Check the diagnosis when practice still feels random
If you understand the explanation but continue making unrelated errors, ask whether the review target is too broad or incorrectly identified. An unfamiliar verb or confusing question format can block a task that appears grammatical. Say which part you can explain and where you lose the thread. A better diagnosis can change the activity rather than simply add more of the same.
Use available memory as context, not an unquestionable verdict
A remembered weak point can make a new session more relevant, but it should remain open to correction. Tell Mocchi when a topic has become easier or when another difficulty matters more today. A useful tutor response changes the next task in light of that evidence instead of repeating a familiar label indefinitely.
Leave one concise clue for the next review
Finish by stating the decision and the clue in a short note. At a later visit, request another example before rereading the old explanation. This gives you a more independent check and helps you see whether the target remains useful. The review succeeds when it makes a previously unreliable choice clearer in new language, not only when the original question becomes easy to recognize.
