The ability to understand and use mechanical devices is critical for a job in many fields.Whether you decide to enter the military, apply for a government job, or take a job in private industry, you’ll have to take an entrance test that determines your skills and abilities. The military requires that all candidates take the ASVAB (Armed Services Vocational Aptitude Battery) test.Many government positions (local, state, and federal) require you to take an entrance level exam that measures your skills. If you want to be a police officer or firefighter, your ability to use mechanical devices and solve spatial concepts problems is very important and shows up on most every test.

Gears and pulleys, map-reading, turn-the-shape—these problems and more appear on all almost all civil service, military aptitude, and vocational/technical entry-level exams. Mechanical and Spatial Aptitude helps students and adults prepare for the exams by strengthening mechanical knowledge—specifically in the areas of spatial relationship, reasoning with symbols, and mechanical aptitude—with a 20-step program that builds vital skills in just 20 minutes a day. This 20-step program uses real world examples that illustrate and strengthen essential skills, plus hundreds of exercises in the same format as standardized tests. This book also includes pre-tests that pinpoint weaknesses, and a post-test that demonstrates the improvement you've made.
