Use COLREGS practice tests to find what to study next
A practice test is most useful when it identifies a specific rule or question type that needs another review session.
Mix the question categories
Use International, Inland and combined questions so the wording of the scenario matters. Avoid studying one narrow category so long that the answer becomes predictable.
Use a demanding practice threshold
COLREGS Prep uses a 90 percent quiz threshold. Treat a passing score as a signal to confirm the result again later, not as permission to stop reviewing.
Review every missed question
Open the rule reference, identify the fact in the scenario that controlled the answer and add the question to a focused review set.
Retest with fresh questions
After targeted study, take another mixed quiz. Improvement across a new set is stronger evidence than repeating the same sequence from memory.
