Prep for your trade's aptitude test, even if it's been years since your last math class.
Flashcard prep built for people who didn't love school the first time around. Real mnemonics, plain language, drawn diagrams, and questions that change every day so you learn the method instead of memorizing an answer key.
Pick your trade
Tap a card to flip it and see what that module covers. One $12 pass unlocks all four.
Not sure which test your local uses? Call the training center and ask. The FAQ below covers what to ask.
See it in action
Every card comes with a memory trick, not just an answer. Mechanical and spatial questions come with drawn diagrams, and the step-through tools let you move the numbers yourself.
Why it works
Not another PDF of drills. Built around how people actually forget and relearn this material.
A memory trick for every rule
PEMDAS, Keep-Change-Flip, "odd gears match, even gears flip": every concept comes with the trick that makes it stick, not just a formula to stare at.
Questions change every day
Numbers regenerate daily and answer positions shuffle, so you learn the method instead of memorizing that "the answer is B."
Diagrams you can actually read
Gears, levers, pulleys, tanks and folding patterns are drawn clearly, and the step-through tools let you move them yourself.
A study plan that adjusts to you
Enter your real test date and the daily card goal and topic rotation recalculate automatically.
Practice that sounds like your trade
Wire colors for electricians, pipe grade and offsets for plumbers, duct stretch-outs for sheet metal, roping and counterweights for elevators.
Small wins, on purpose
Daily milestones and streaks make five minutes of practice feel worth showing up for, even on a bad day.

Questions
The short answers.
Does one $12 pass cover every trade?
Yes. One code unlocks all four trade modules for 12 months. Switch between them any time from the Trade menu at the top of the app, which is handy if you're applying to more than one apprenticeship.
My local's test looks different. Will this still help?
Probably. Plumbing, pipefitting and sheet metal locals choose their own tests, so sections and timing vary. Math, often through first-year algebra, is on almost every one, and many add reading, mechanical reasoning or spatial reasoning. The electrical and elevator tests are standard nationwide. Call your training center and ask three things: which test they use, how long it is, and whether calculators are allowed.
Can I use a calculator on the test?
Not on the electrical test, and many other programs don't allow one either, so every question here is written to be solved by hand, with a shortcut for doing it quickly. Check with your local to be sure.
Does it work on my phone?
Yes. It runs in any phone or computer browser with nothing to install. Your code unlocks the device you redeem it on.
Is this connected to a union or training center?
No. TradeEntrance is an independent study tool. It isn't affiliated with or endorsed by any union, joint apprenticeship committee or training center, and it can't guarantee a score.
