TradeCert
CDL and EPA Section 608 practice tests that work anywhere — in the cab, in the yard, in a mechanical room with no signal.
What you get
Explanations, not just answers
Every question tells you why the answer is right, citing the rule or the number behind it — so you learn the material instead of memorising letters.
Timed mock exams
Full-length simulations under a countdown, drawn from the whole bank, so you know how the real thing feels before you sit it.
Genuinely offline
The entire question bank ships inside the app. No signal, no data plan, no problem.
Progress tracking
Best score and attempt history per category, so you can see which topics still need work.
A generous free tier
Forty percent of every category is free forever — over a thousand questions before you are ever asked to pay.
