What people are saying
Quotes representative of outcomes observed with WorkUgo users · real named reviewers coming soon.
Oil-sands mining equipment for 8 years. The hydraulics theory was my gap — practical fixes I know, the flow-and-pressure questions trip people up. Two months of drills here and I passed at 79%.
Bryce N.
Heavy Duty Technician, Fort McMurray AB
Ag equipment dealership tech. The electronic controls and CAN diagnostics questions are the same ones on the exam — the explanations are clearer here than the OEM training I'd had. Cleared at 80%.
Liam G.
Red Seal HD Tech, Regina SK
Mining contractor apprentice. Drivetrain and undercarriage were the weak areas on my practice. The explanations on planetary gearsets were the first ones I really understood. Passed at 75% on first write.
