The skills test starts with the walk-around

You only get credit for what you say out loud. Mr. Egg walks you around the truck, one checklist item at a time, and tells you exactly what the examiner wants to hear.

  • A short video lesson for every Class A checklist item
  • Spanish explanation under every English script
  • A timed mock inspection scored by an AI examiner

Readiness score

Know whether you are ready before you pay the testing fee

Every answer feeds a weighted score across the subjects your license 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.

Progress and accuracy by subject
