The WTMA is a specialized hurdle. Generic prep leaves you guessing.
Applying for a mechanical, technical, or skilled trade position? The Wiesen Test of Mechanical Aptitude (WTMA) is a critical step in the hiring process, and it is unlike any other mechanical test you have seen. Most candidates walk in cold, never having seen the specific question style or the way concepts are applied. They rely on generic prep books that cover a little of everything, but nothing in the depth or format that the WTMA demands.
The stakes are high: your score determines whether you move forward in the hiring process. Without targeted preparation, you risk being caught off guard by the test's unique emphasis on practical, real-world mechanical reasoning. You need a prep resource that is built specifically for the WTMA, one that mirrors its format and difficulty so you know exactly what to expect.
Built for the WTMA, not just any mechanical test
This guide is the only exclusive WTMA prep on the market. It is not a catch-all for multiple tests. Every question, every explanation, every review section is designed to match the Wiesen Test's question style, difficulty, and topic emphasis. You get 420 practice questions across seven full-length tests, each with detailed explanations that show you the reasoning, not just the answer.
The content is organized around the exact domains the WTMA covers: forces and motion, simple machines, electricity, fluids and hydraulics, and spatial reasoning. You also get 600 digital flashcards and a full audiobook for flexible study. This isn't just a book; it's a complete system that helps you master the concepts employers actually test for.
A simple, structured approach to your WTMA prep
- 1Diagnose your weak areas with the first full-length practice test.
- 2Study the focused review sections for the domains you need to improve.
- 3Drill with the remaining practice tests, simulating real exam conditions.
- 4Review the detailed explanations to reinforce your understanding.
- 5Use the Digital flashcards and audiobook for on-the-go review and final preparation.
