Plumbing Apprenticeship Aptitude Test Sample Questions and Answers
Plumbing Aptitude Test Section #1 - Reading
The Reading section assesses your ability to read and comprehend texts, as well as draw conclusions from them. The section contains 42 questions to be solved in 25 minutes. Each question has 4 answer options, only one of which is correct.
Reading Sample Question
The exponential growth and development in the services and activities of search engines during the past decade has brought about a number of challenging legal issues in the area of copyright law. While search engines are continuously expanding their reach, copyright law has largely failed to adequately respond to these technological advancements. Rather, the current situation is one of rigid, outdated copyright laws being applied to online activities, which were never contemplated when the original legislation was drafted – causing great ambiguity. Search engines have the crucial role of ensuring the free flow of the internet’s core purpose – access to information. However, by their very nature, copyright laws fundamentally challenge this concept of a freely flowing and accessible internet.
Which of the following statements regarding copyright law is correct?
The Plumbing Aptitude Test Practice contains dozens of reading practice tests to become familiar with the most common techniques used in them.
Plumbing Aptitude Test Section #2 - Numerical Computation
The Numerical Computation section of the Plumbing Aptitude Test assesses your ability to calculate quickly and accurately without using a calculator. It contains 28 questions on two topics: fractions and decimals. Each question has 5 answer options, only one of which is correct.
Numerical Computation Sample Question
Convert 3/13 into decimal.
The Plumbing Aptitude Test Practice combines hundreds of questions with basic math study guides to make you as proficient in calculations as you can possibly be!
Plumbing Aptitude Test Section #3 - Numerical Reasoning
The Numerical Reasoning section assesses how well you identify numerical patterns. This section contains 10 number series questions to be solved in 10 minutes. Each question has 5 answer choices, only one of which is correct.
Numerical Reasoning Sample Question
0 , 3/4 , 8/9 , 15/16 , 24/25 , ?
The Plumbing Aptitude Test Practice addresses all types of number series so you can identify them super-fast on the actual test.
Plumbing Aptitude Test Section #4 - Folding
Folding questions measures your ability to visualize three-dimensional shapes. It contains 12 questions to be solved in 15 minutes. Each question
Folding Sample Question
The Plumbing Aptitude Test Practice comes with a built-in spatial reasoning preparation covering 120 practice questions in multiple types, to improve your 3d visualization ability!
Plumbing Aptitude Test Section #5 - Problem Solving
The Problem Solving section of the Plumbing Apprenticeship Aptitude Test assesses your ability to solve mathematical word problems. These may include basic arithmetic calculations, percentages, or geometry, yet the main challenge is to convert the problem from a verbal one to a mathematical one. This section contains 35 questions to be solved in 35 minutes. As in all numerical sections, questions have 5 answer options each, only one of which is correct.
Problem Solving Sample Question
A man walked at a pace of 5 mph for 3 hours and then ran at a pace of 8 mph for half the time. What was the total distance in miles that he covered?
The Plumbing Aptitude Test Practice contains a specific preparation for word problems that allows you to master the crucial trait of verbal-to-math transition.
Plumbing Aptitude Test Section #6 - Mechanical Comprehension
The Mechanical Comprehension section measures your ability to understand and apply mechanical principles. These questions, similar to what you will see in mechanical aptitude tests such as the famous BMCT usually do not require any previous knowledge, but an understanding of basic physics will tremendously help. The test contains 13 questions to be solved in 13 minutes.
Mechanical Comprehension Sample Question
In which way is the wagon accelerating? (If neither, mark C.)
The pendulum is moving backward; therefore, the car is accelerating in the opposite direction.
What happens when an object is in an accelerating system, in the same way, you feel pulled back when the car is speeding up or forwards when it is braking.
Remember the physical principle: When an object is within an accelerating system (another object that accelerates or decelerates), the inner object's force will be in the direction opposite to the acceleration.
The Plumbing Aptitude Test Practice teaches you the physical principles behind the questions so you can solve ANY mechanical question on the actual test.
