Practice and completion
Practice is unlimited and includes explanations. Worked tasks ask you to show inputs, a method, units, an independent check and interpretation. The readiness targets and rubric support self-study; they do not issue a graded pass or prerequisite waiver.
Formal course enrollment, account-saved completion credit, shared program credit and certificates are not available. These lessons do not establish academic credit, CEUs, professional certification, examination readiness or workplace authorization.
