The exam is four calculations. Own all four.

11lessons across four study days, a check closing every lesson. The course teaches the exam-room method exactly as you'll sit it — the almanac's altitude-correction card, the daily pages and increments, Pub 249 entering rules and Table 5, z to Zn, the intercept and the plot — then the azimuth check, latitude by meridian passage, and the amplitude. The interactive workbench and exam-question calculators are built into the lessons. Pass a check to mark a lesson complete; progress is saved on this device.
