About this app

Plumber exam prep built around one question: what have you not studied yet? The 18 exam-assessed tasks of the national plumber standard form one checklist, so you prepare for the interprovincial plumber exam by closing gaps. Not a government app.

- 18 study notes distilling the high-yield points.
- 180 flashcards for the facts you have to recall cold.

A CHECKLIST OF THE 18 EXAM-ASSESSED TASKS
Each of the 18 exam-assessed tasks has a skim note, a flashcard deck and a quiz, and turns green only when all three are done. Calculation questions — grade, fall, expansion, fixture units — show the working step by step, so the plumber practice test doubles as a trade-math refresher.

- Apprentices at their final level — what many still call the journeyman plumber exam.
- Experienced plumbers challenging the interprovincial plumber exam.
- Anyone wanting plumbing exam prep that explains the wrong options too.
- Candidates planning a plumber exam 2026 sitting.
