The product in six parts, then how the trial works.
7 days free, then $9.99/month. Cancel anytime.
Practice questions
Start a daily mix, or a run in a category. Each answer opens an explanation of the correct choice, and you can ask the AI tutor about any question.
Timed drill
Practise against a running clock, mark questions to revisit, then review your result by category. The drill is practice material, not an official exam; see the Exam page for the Section 608 structure and confirm current details with your certifier.
Flashcards
One deck per category, plus a curated mix. Tap a card to reveal the answer, and mark the cards you want to see again.
Service procedures
16 procedures as numbered steps. Critical steps carry a text tag, with the common mistakes beside them.
Leak Rate gauge
Work out a leak rate and read it against the threshold on a gauge, with the regulation paragraph shown under the reading.
AI tutor
Ask about a procedure, a rule or a practice question. Answers are study aids: check the regulation text before you rely on them.
