Nine knowledge tests, scored the way your state scores them.
Know whether you are ready before you pay the testing fee
Every answer feeds a weighted score across the subjects your licence class actually requires. Coverage, accuracy and recency each count — so one lucky run does not inflate it.
- Coverage — how much of your required syllabus you have actually seen.
- Accuracy — weighted so recent answers move the number more than old ones.
- Consistency — a subject you get right once does not count as learned.
Estimated readiness only. No study aid can guarantee a pass, and we do not claim one.
How it works
Pick your state
Pass marks, question counts and retest waits are set by the state, not by us. Choosing yours changes the questions where the manuals disagree.
Practise by subject
General Knowledge plus whichever endorsements your job needs. Every answer comes back with the rule behind it, not just right or wrong.
Track readiness
Keep going until the score stops moving. That plateau is the signal to book the test.
