Most practice scores answer one question: how many attempts were correct. They do not show how much of the question bank was seen. A learner can score 17 out of 20 85% while repeating the same 20 questions; against 158 General Knowledge questions, unique coverage would be about 13%. That should trigger more study, not a pass prediction. I built CDL Quest around separate signals for accuracy, unique-question coverage, and recent practice evidence, plus missed-answer repair. I would especially value feedback from CDL learners and instructors: what is more useful when choosing what to study next topic-level coverage, a missed-question queue, or a plain list of unseen concepts? CDL Quest is an independent study aid, not an official exam source or pass guarantee.
CDL Quest turns 610 source-cleared questions into route-aware CDL permit practice, missed-answer repair, recall-first pre-trip drills, and coached road decisions. Starter includes all 158 General Knowledge questions free. It is an independent study aid—not an official exam source or pass guarantee.
