OOW Prep
Module Pre-Study

Plot the work before you start it.

These are focused self-study tracks for the classroom module you are about to sit. Each route shows its real estimated workload. A session is a chapter-sized pacing suggestion, not a full day.

Coverage on the chart

Choose the track that matches your next classroom module. You do not need to work all eight. Every lesson ends with a marked check and stores progress on this device.
