Three realistic ways to prep for the UA pipe-trades aptitude test. JobTestPrep and Mometrix are established general test-prep vendors; PipePrep AI is a specialist built only for the GAN-style six-section battery. Here is how they actually differ.
| PipePrep AI | JobTestPrep | Mometrix | |
|---|---|---|---|
| Built specifically for the UA/GAN battery | Yes — the only thing it does | No — general aptitude packs cover similar skills | No — general trade-apprenticeship study guides |
| Full six-section timed batteries | 10 batteries, 133 questions each, per-section timers and scores | Practice sets by skill area; not structured as the six-section battery | Study guide + practice questions; not structured as the six-section battery |
| No-calculator arithmetic training | Yes — every question is designed for hand arithmetic, plus timed speed sprints | Skill-dependent; some material assumes a calculator | Skill-dependent |
| Paper folding (spatial) practice | Yes — 120-item bank plus an interactive folding tutorial | Yes — spatial reasoning packs available | Limited |
| Mechanical comprehension | Yes — 130 Bennett-style items with explanations | Yes — mechanical aptitude packs available | Yes |
| AI tutor | Yes — Piper explains any missed question in trade language | No | No |
| Trade-specific tools | Pipe Offset Calculator (free), takeout/cut-length, interview prep for UA orals | No | No |
| Free tier | Free web practice tests; app free tier has 2 full batteries + offset calculator | Limited free samples | Limited free samples |
When a general vendor makes sense: if you want printable PDF-style study packs, you study best from a book, or you are prepping for several different exams at once, JobTestPrep and Mometrix are legitimate, long-standing options and their skill coverage overlaps the GAN battery.
When PipePrep AI makes sense: if you want your practice to feel like the actual test day — six sections in the real order, each under its own clock, no calculator anywhere — and you want every miss explained. Most UA locals rank applicants by score and fill classes from the top down, so the goal is not passing; it is out-scoring the rest of the list.

The prep that matches the real format: six timed sections (reading, numerical computation, numerical reasoning, problem solving, paper folding, mechanical comprehension) with no calculator. PipePrep AI is built only for that battery, with 10 full-length six-section timed practice tests. General vendors like JobTestPrep and Mometrix sell broader aptitude banks that cover the same skill areas but are not structured as full GAN-style batteries.
No. PipePrep AI is fully independent — not affiliated with, endorsed by, or connected to the United Association, any UA local or JATC, or GAN Human Resources. All questions are original practice items, never copied from the real exam.
They can. Both are established test-prep companies whose materials cover reading, math, mechanical, and spatial skills. If you prefer PDF-style study packs or already use one for another exam, they are reasonable options. The trade-off is format match: neither is organized as the six-section, per-section-timed GAN battery, and neither includes pipe-trades-specific tools or an AI tutor.
The web practice tests on pipeprepai.com are free with no account. The mobile app is $14.99/month or $79.99/year after a 7-day free trial; the free tier includes two full practice batteries and the Pipe Offset Calculator.
Ten full-length pipe-trades batteries, a tutor that explains every miss, scored mock interviews, and free field tools — for less than a single generic prep package.
