Mastery Guide
Learn how word progress works in Learn-Lang, what each learning state tells you, and what actions help a word move toward stable recall.
Learn-Lang tracks each word separately. The state of a word is not a label for how smart a learner is. It is a practical signal about memory strength and what the next action should be. The more consistent your recall, the higher the mastery level and the longer the spacing between reviews.
These are the learner-facing buckets you see in analytics and review flows.
These are words with mastery level 1 to 3. You have started recalling them correctly, but the app still treats them as in progress.
Keep answering them correctly in review and new-word sessions until they build enough repeated recall to reach mastered.
These are words with mastery level 4 or higher. In practice, that means you have recalled them correctly enough times for the app to trust longer spacing.
Do not ignore them. Daily review keeps mastered words fresh so they stay retrievable instead of quietly decaying.
These are words flagged because errors are high or the next review is overdue. They are the words most at risk of being forgotten right now.
Run weak-word drills and daily review, then rebuild the word with repeated correct answers so it can move back into learning and later mastered.
Mastery is based on consecutive correct answers for the same word. The level is the internal signal behind the visible word buckets.
No correct streak yet. The word has not started building mastery.
1 correct answer in a row. The word has entered the learning stage.
3 correct answers in a row. Recall is improving but still in progress.
5 correct answers in a row. The word is close to graduating.
7 correct answers in a row. The word counts as mastered.
A word changes state because of recall performance over time, not because you opened the app or looked at the card once.
A word starts moving once you answer it correctly. The first correct answer creates a streak and moves it out of the untouched state into active learning.
Mastery is earned through repeated correct recall. In Learn-Lang, mastery level 4 is reached after a seven-answer correct streak for that word.
A word is flagged when wrong answers pile up or when its scheduled review is overdue. That is the app saying the memory is no longer stable enough to trust.
The state is useful only if it changes what you do next.
Keep practicing it in daily review and new-word sessions. Your goal is repeated correct recall in both directions, not just one lucky answer.
Let the spaced schedule do its work, but keep showing up for daily review. Mastered means the word earned longer spacing, not permanent immunity from forgetting.
Prioritize weak-word drills and daily review. This is the app highlighting the words most likely to break first unless you repair them with fresh correct answers.
The review interval grows from a combination of streak length and answer quality.
The first correct answer keeps the next review soon to reinforce recall quickly.
After the second correct answer, spacing grows based on your ease factor and recent quality.
Incorrect answers reset the streak and return the word to the shortest interval.
Learn-Lang measures answer quality to adjust spacing gently without changing the mastery thresholds.
Only correct answers advance the streak. Incorrect answers reset the streak and shorten the next interval.
Higher confidence boosts answer quality. Low confidence lowers quality and slows future spacing.
Fast responses slightly improve quality, while very slow answers reduce it.
Learn-Lang tracks strength in both directions: source language to English, and English to source language. Each direction improves independently based on the answers you give in that direction. A word is not truly strong until recall is reliable in the directions you want to use.
