Mechanical Comprehension

Mechanical Comprehension

Part four is to test your understanding of basic mechanical principles using both mechanical elements e.g. gears and pulleys, and domestic objects e.g cars. Each item has a written question supported by a technical drawing.

To make the most of this practice test, keep track of the timer onscreen and plan your answers accordingly. Your score is calculated solely on the number of correct answers you achieve, so if you get stuck move onto the next one and revisit if you have time. In exam conditions you would have five minutes to complete this number of questions. On the day you will have 10 minutes to complete 30 questions. On the next page you will have 3 minutes to complete 8 questions, this allows you slightly more time to practice and get to know the test.

Your time is up and all questions have been disabled. Please submit your test to see your mark.
