Choose a learning stage
These prerequisites are study recommendations, not access restrictions. You can open any resource and return to earlier lessons whenever you need.
Need targeted ADAS practice?
Use the Skills Gap & Remediation Center for personal confidence checks, original formative cases, and matching lesson/lab recommendations. It does not import online scores or instructor observation records.
Open Skills Gap & Remediation Center →Applied Lab 04 · Verify the procedure before planning service
Review four fictional work orders, challenge generic service claims, and assemble a vehicle-specific research packet for instructor review. This optional resource is not an extra graded journey stage.
Open OEM Research & Decision Lab →Applied Lab 05 · Troubleshoot an unsuccessful calibration
Use fictional evidence to separate setup problems, mounting concerns, unsafe road conditions, and an unresolved system warning after a completed routine. Optional ungraded practice.
Open Calibration Failure & Recovery Lab →Personal learning plan
A printable study plan. It records only self-review and private reflections from this browser. It does not import assessment results, instructor sign-offs, credentials, or calibration records.
