Completion and competence answer different questions
Completion asks whether you carried out a defined activity. Competence asks what you can understand or produce under particular conditions. A checkbox can record that you answered a set of questions, but it cannot capture every future context in which the language might appear. Keeping the distinction clear helps a study plan remain useful without turning it into a claim that every finished topic is permanently mastered.
This is also why one difficult review should not erase the value of earlier work. You may need less support than before, notice the relevant clue sooner, or make a more precise mistake. Record those changes rather than reducing progress to either perfect performance or total failure.
A changed example reveals more than a repeated layout
If a completed task used 学校に行きます, 'I go to school,' try a different destination or a sentence in which the place has another role. 学校で勉強します, 'I study at school,' asks for a different decision. Recognizing the original example is useful, but explaining the new choice shows whether the relevant relationship is available beyond the task you already finished.

| Japanese | Romaji | Meaning |
|---|---|---|
| 学校に行きます。 | Gakkō ni ikimasu. | I go to school. |
| 学校で勉強します。 | Gakkō de benkyō shimasu. | I study at school. |
Record the amount of support you used
An answer produced after a hint is not the same as one retrieved independently, and both can be part of learning. Tell Mocchi whether you needed the translation, a first-word cue, or the full model. This gives the next review a better starting point. It also prevents a sequence of supported successes from being mistaken for evidence that no support is needed anymore.
Use delayed recall without turning it into punishment
Return to a small number of earlier points after a gap and attempt them in a fresh context. If a point is difficult, identify the clue that would help and practice it again. The purpose is to discover what needs attention, not to invalidate completed tasks. A calm review gives you more useful information than repeatedly testing yourself until you happen to get a perfect run.
Let the next step reflect the evidence
If the new example is easy and your explanation is accurate, move to a related challenge while retaining occasional mixed review. If the same decision remains unstable, keep the next task narrow. Mocchi can help connect practice results to a plan, but the record is strongest when you state what actually happened: the task completed, the help needed, and the specific language point to revisit.
