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.
Use the lesson tools
Start the play/pause reader above or below the lesson text and use stop when needed. Text stays readable when speech is unavailable. Calculator links open separately. Read a formula with its definitions and units; record your own calculation before opening feedback.
