- Content level: ChallengeEnrichment or more demanding reasoning within high school chemistry.
Content level is separate from question difficulty.
Topic mastery
0 of 9 lessons marked completed. Mastery comes from graded practice, independently of lesson completion. Progress is saved on this device.
How the levels work
Not assessed → Developing → Proficient → Mastered. Proficient requires 5 of the latest 6 different independent questions correct, plus independent success on 2 medium or hard questions. Mastered adds 2 new correct answers in mixed practice at least 24 hours later. Hints and retries remain useful practice, but do not establish proficiency. Review reminders do not lower a level.
