Frequently Asked Questions
Why are the prices higher than other prep courses?
Because this isn't a video course — it's a career accelerator. Operators who pass Class 3 or Class 4 typically earn $85K–$130K+. Your Practice Pass costs less than one day's pay at that salary. We price based on outcome value, not content volume.
Do the Practice Passes expire?
No. Your access never expires. Pay once, practice as many times as you need until you pass.
Are the questions based on real exam content?
Yes. All questions are written by certified operators and aligned with OWWCO, EOCP, and provincial exam syllabi. Every calculation question includes a full step-by-step AI-explained solution.
What makes Echelon different from free study materials?
Free materials give you content. Echelon gives you adaptive practice, instant AI explanations for every wrong answer, timed mock exams that simulate the real thing, and a score history that shows exactly where to focus. The difference is passing vs. re-booking.
What payment methods do you accept?
All major credit and debit cards (Visa, Mastercard, Amex) via Stripe's secure checkout.
Can I get a refund?
We offer a 7-day money-back guarantee if you're not satisfied. Email [email protected].
