The IUEC aptitude test was the first union test I prepared for seriously.
The test I took had a few main sections:
- Reading
- Math
- Mechanical comprehension
- Tool identification
The reading section was the easiest part for me. That does not mean it should be ignored, but I saw it as a place to collect points.
The mechanical section was more interesting. I studied with Bennett mechanical comprehension material and used a phone app called Bennett Test Full. That helped me get used to the style of questions: gears, pulleys, basic force, movement, and common sense mechanical relationships.
The tool identification section was pretty straightforward for me because I have some hobby mechanic experience. Still, I would not walk into it cold. You should know common hand tools, basic measuring tools, and what tool makes sense for a simple job.
The part I took most seriously was math.
That was the section that made me feel the least comfortable.
It included algebra and some geometry. No calculator. Scratch paper was allowed, but you had to manage time and keep your head clear.
I used YouTube to review basics. I also paid for a structured practice course because I know myself. If I just say, “I will study math online,” I can drift. A course gave me problems, timing, and a clear place to start.
You do not have to pay for a course.
There are plenty of free resources if you search for trade aptitude test math, mechanical comprehension, or elevator aptitude practice.
The important part is doing timed practice.
Knowing how to solve a problem slowly at home is not the same as solving it under a timer while you are nervous.
If I were studying again, I would focus on:
- Fractions
- Decimals
- Percentages
- Basic algebra
- Basic geometry
- Reading a tape measure
- Mechanical reasoning
- Common hand tools
The test is pass/fail, at least in the process I went through. That can make it feel simple, but do not let that fool you.
You still have to pass.
And when you are sitting there with the timer running, you will be glad you practiced.
