Lesson Check
ol_learn_checkRead-only
Grade the learner's answer to a LEARN check. item 'self_check' with section (the check's step index) and selected_option (0-based) is graded on the server for every caller, no key needed, and returns correct, correct_option and the lesson's own explanation, which you relay as written. The module quiz (item 'quiz') and the apply task (item 'apply') are not graded over MCP yet: they answer graded: false and the lesson continues. Submit ONLY the option the learner chose, never your own pick; pass hint_used: true if they asked for the hint. A step that is not a self-check, or an option out of range, is refused (INVALID_PARAMS). Stateless: nothing is stored. Source: Oxford Ledge LEARN (authored); FREE.
