Learning-System Transparency

Source first, variation second
Dynamic Learn begins with the material on your source cards. Recognition, direct recall, and simple source-grounded activities build familiarity before harder variations and transfer activities become eligible. A structured format does not bypass this progression.
The runtime prepares questions and fallback activities ahead of use. If new preparation is delayed, ready source questions can continue; a new round is introduced only at an answer boundary. Earlier questions may deliberately return. This is planned retrieval, not evidence that your answer was lost.
What counts as learning evidence
Correctness, partial credit, assistance used, format, time since earlier practice, and known-concept mix-ups inform scheduling. Hints reduce evidence weight. Seeing an answer or a teaching exposure does not count as unaided recall. A few correct answers in one sitting do not establish lasting mastery.
Dedicated Flashcards can use self-ratings. Dynamic Learn uses objective grading or zero-evidence teaching exposure. Uncertain answers and unsupported scientific cases should remain uncertain rather than become false proof of success or failure.
Structured activities and models
A temporary masked diagram, blank matrix cell, graph alternative, or other question view is derived from source content without overwriting it. Generated wrong alternatives are question artifacts, not new curriculum concepts. Pairwise Knowledge Map evidence comes from actual source concepts involved in an activity.
Some Plus features use models for source-grounded variations or semantic review. Native validators and deterministic graders are used where possible. Scientific equivalence depends on the supported representation; a molecular formula alone does not establish connectivity or stereochemistry.
Your control
The Knowledge Map summarizes accumulated evidence. Color, size, rings, and edges have specific meanings described in the map legend. It is not a measure of intelligence or a clinical assessment. Home shows currently relevant material, while Progress retains learning history.
You can inspect a question's source, report a problem, challenge a grade, choose available formats, and reset progress. Sharing content does not share your individual learning record. Recommendations and sleep-window suggestions remain optional assistance.
