Getting Started
You're preparing for the UA Plumbing & Pipefitting Pre-Apprenticeship Aptitude Test. This site was built by someone who passed it on his first attempt. Here's how to use it.
It's a 4-section aptitude test that determines whether you get into the apprenticeship program — and where you rank on the list. Higher score = earlier call. Here's what you're up against:
4
Sections
Reading Comprehension, Figure Visualization, Mechanical Abilities, and Math. Each is scored independently.
~4 hrs
Total Time
Roughly one hour per section, with short breaks. It's a long day — mental stamina matters as much as knowledge.
70%
Per Section Minimum
You must score 70% or higher on every section. Fail one and you retake the entire test — with a 6–12 month wait.
Pencil
Paper Only
No calculator, no phone, no scratch paper beyond what they give you. Everything is done by hand — including all math.
Rank
Score = Priority
Your score determines your position on the eligibility list. A 90% gets called for an apprenticeship slot long before a 75%.

Official Study Guides
UA 246 says: “We do not offer a study guide.” That's why this site exists.
UA Test Prep follows a learn-then-test approach. Study guides teach you the concepts and strategies. Practice tests measure whether you've actually learned them.
Step 1
Each section has a dedicated study guide with strategies, worked examples, and interactive demonstrations. Start here before you touch a practice test. Understanding the format is worth 10 points by itself.
Step 2
Once you understand the concepts, test yourself under realistic conditions. Timed. Pencil and paper. No calculator. Every question includes a detailed explanation so you learn from your mistakes, not just your score.
Each section tests a different skill. You need 70% on every one. Click through to the study guide for strategies and examples.
Read a passage, passage gets removed, answer True/False questions from memory. Tests retention, not speed-reading.
Mental paper-folding, shape rotation, pattern matching. Spatial reasoning — no math required, but you need to see it in your head.
Gears, pulleys, levers, fluid dynamics, basic physics. If gear A turns clockwise, which way does gear D turn? That kind of thing.
Arithmetic, fractions, percentages, geometry, word problems — all by hand, no calculator. This is where most people struggle.
You don't need to study 8 hours a day. Consistent, focused sessions — 45 minutes to 1 hour daily — will get you there. Here's a proven structure.
