How the SMART Quiz works
Unlike random flashcard apps, SteamTicket’s adaptive engine builds every session from your own results. Units where you score below 70% get pushed to the front of every session until your score climbs into the green. Questions you missed come back at increasing intervals, and you can see your running score for every unit before mock exam day.
Your Path to Success
Weak units first
Units where you score below 70% get pushed to the front of every session until your score climbs into the green.
Spaced re-asks
Questions you missed come back at increasing intervals. Questions you know well fade into light review so you stay efficient.
Per-unit progress
See your running score for every unit across all your sessions. Know exactly where you stand before mock exam day.
Keeps going if signal drops
Study on any device. Once a course is open it keeps working if your signal drops mid-session; you need a connection to open a course. Your progress syncs when you reconnect.
Unlimited mock exams
Timed mock exams with full review after every attempt. 100-question, 3-hour sittings on papers that use that official format.
A refund, plus support if you don’t pass
30-day money-back guarantee. And if you don’t pass, we keep your access open at no charge and help you target what to review.

What is SteamTicket, and what isn't it?
What SteamTicket is, and what it isn't
SteamTicket is:
- Practice questions for your trade exam, organised by unit, with an explanation for each answer.
- Timed mock exams for the standard SOPEEC multiple-choice papers: 100 questions in 3 hours, marked against the 65% pass mark. 313A uses 125 questions in 4 hours, with a 70% pass mark. 1st Class practice on papers A1 to A4 and B1 to B3 is multiple choice on the syllabus and does not match the long-answer paper.
- A way to test yourself. SMART Quiz brings back the questions you miss, and your progress shows which units need more work.
- Made by Jax & Noah Studios Inc., an independent Canadian company.
SteamTicket isn’t:
- A textbook or a course. You learn the material from your course or training materials.
- Affiliated with or endorsed by SOPEEC, ABSA, TSSA, Technical Safety BC or any regulator, or by NAIT, SAIT or BCIT.
- A copy of the real exam. Every question is original, written to the public syllabus.
- A promise of a pass. It shows you where you stand, so you can focus your study.
