Field notes
The practice-test description specifies a 50-question format, a 90% pass mark, mixed Inland and International material, and a three-and-a-half-hour clock. The games tag answers to the Rules they test, while the page distinguishes BUOYED as covering aids to navigation outside the Rules. Its six listed calculators include CPA from two fixes and set and drift; the site says the relevant formulas are tested against worked examples in Bowditch and the Coast Guard Light List.
