The tests
The free sample has one code lookup, one drainage sizing problem and one vent sizing problem, each worked line by line. It runs in the same test player as the full mock: a question palette, mark for review, a clock and a summary before you submit. Practise with your IPC 2024 and IFGC 2024 open beside you, as Oklahoma's open-book exam allows; check your own board's rules.

The number of mock questions in each area is the number the Oklahoma bulletin lists for that area. Each area set and the sizing set run at about the mock's pace, 2.2 minutes a question.
Every answer names its code section. Each explanation names the IPC 2024 or IFGC 2024 section or table it rests on, such as Table 709.1 for drainage fixture units, Table 909.1 for trap-to-vent distance or Section 604.8 for pressure-reducing valves, or the 29 CFR 1926 section for a safety question, so you practise finding it in your own code book. We cite the codes; we never reprint them.
Every sizing problem is worked line by line: drainage fixture units, building drain, branch, stack and vent sizing, water supply demand and friction loss, gas pipe sizing and combustion air, each with the table value and every step.

How it is scored
- One mark per correct answer. The Oklahoma bulletin sets the pass mark at 70% correct from 1 November 2026, so the results page shows where you stand against 70% on our questions.
- Your score in each outline area, with your time per question, so you can see which area costs you the most marks.
- Code sections to reread: the IPC 2024 or IFGC 2024 section (or the 29 CFR 1926 section) behind every question you missed, grouped by outline area, with a link to the International Code Council's free read-only view of the 2024 code or to the eCFR.
- The reason behind every answer, and your progress across retakes.
Your percentage here is your score on our questions; it does not predict an exam result.
The outline this follows, from the official bulletin
- Oklahoma's Plumbing Journeyman and Natural Gas exam is 85 questions in 180 minutes. The bulletin sets the pass mark at 64 correct (75%) and, from 1 November 2026, at 60 correct (70%). Up to ten unscored experimental questions may be added, and the time for them does not count against you (PSI bulletin, effective 11 September 2026).
- It is open book. The references are the International Plumbing Code and the International Fuel Gas Code with Oklahoma revisions; Mathematics for Plumbers and Pipefitters (Lee Smith, 8th edition); and 29 CFR Part 1926 (OSHA construction), or PSI's selections from it. Books may be highlighted, underlined and tabbed with permanent tabs, but nothing may be written in them. A silent, battery-operated, non-printing, non-programmable calculator without an alphabet keyboard is allowed.
- The bulletin lists the 2018 IPC and the 2018 or 2024 IFGC, says the 2024 codes may be used from 8 October 2026 and says the 2018 codes are no longer allowed from 14 December 2026. The Construction Industries Board's notice of 31 August 2026 allows either edition from 8 October 2026 to 8 January 2027 and only the 2024 codes from 9 January 2027. If you test between those dates, confirm with the Board which edition you may use.
- The fee is $92 for each examination portion. A candidate who does not pass gets a diagnostic report. After a first failed attempt you wait 30 days before retesting; for exams other than electrical, from the second failure on you wait 90 days.
- The Construction Industries Board decides who may sit the exam (testing and exam information). The 2024 IPC and IFGC can be read free, read-only, on the International Code Council's site (IPC 2024, IFGC 2024).

Before you buy
Are these real exam questions?
No. Every question is our own, written from the International Plumbing Code and International Fuel Gas Code (2024 editions) and 29 CFR Part 1926 and arranged by the outline in the Oklahoma PSI bulletin. None comes from a PSI or state exam.
Will this match my state's exam?
It gives IPC 2024 practice that follows the Oklahoma PSI outline, so it suits candidates whose state exam uses the 2024 IPC. States adopt different codes (IPC or UPC) and editions and set their own length, time and outline, so check your board's candidate bulletin for differences.
Do I need my own code book?
It helps. Oklahoma's exam is open book (check whether yours is), so the best practice is to look each answer up in your own IPC and IFGC as you go. Every explanation names the section to find, and the International Code Council offers free read-only access to the 2024 editions online.
Is this made or recommended by PSI, the ICC or a state board?
No. It is independent practice by ProSyllabus. International Plumbing Code and IPC are registered trademarks of the International Code Council.
Will this make me pass?
We do not claim that it will. It gives you timed practice on a published outline, your score by area on our questions and the code section behind every answer, so you can see where to study.
What do I get?
A full mock of 85 questions with a 180-minute clock, a sizing and calculations set of 34 questions and a set for each outline area, 249 questions in all with the free sample, in the full test player. After each test: your score by area, the IPC, IFGC or 29 CFR 1926 sections to reread, your time per question and the explanation of every answer. Retake any test as often as you like.
How do I pay and get access?
One payment by card (or PayPal where offered), handled by our payment provider. In the United States the price is charged in US dollars; in Canada, the United Kingdom and the euro area in your own currency; elsewhere in your own currency where we support it, otherwise in Indian rupees with the local figure shown as an estimate. Access opens on this device straight after payment. Sign in afterwards to keep it on your account. Purchase policy.
