What is the Bennett Mechanical Comprehension Test (BMCT)?

The Bennett Mechanical Comprehension Test (BMCT) is an assessment developed by Pearson Assessments. The BMCT is used as a prerequisite during the employment process for many technical roles.

This test intends to seek out individuals with good mechanical reasoning abilities and includes questions covering your mechanical aptitude, spatial visualization, application of physics and ability to deduce how things work.

The original BMCT consists of 68 multiple-choice questions and has a 30-minute time limit. The updated BMCT II consists of 55 multiple-choice questions and has a 25-minute time limit. It is administered online only.

BMCT Time Limit

The BMCT, like many other psychometric tests, is administered under strict time constraints. The original BMCT consists of 68 multiple-choice questions that need to be answered in a 30-minute timeframe. The updated BMCT II, on the other hand, consists of 55 multiple-choice questions that will need to be answered in a 25-minute timeframe. The most common version of these tests that you will encounter during the recruitment process is the BMCT II.

BMCT Pass Mark

The BMCT scoring process is based on item response theory (IRT). Since the questions on the BMCT are often randomly compiled through an item-banked system of 300+ questions, the IRT has been found to be the most ideal method of scoring.

This form of scoring can adapt to minor differences in difficulty between item-banked test versions so that scores are equivalent across organisations. Once you have completed the BMCT, the company will receive a comprehensive score report from Pearson. This report will represent your final score in a variety of ways; they are:

  • Percentile Ranking
  • Raw score (number answer correctly)
  • T-score
  • STANINE Score
  • STEN Score

Your score can tell potential employers whether you are scoring in an appropriate range for your job level and if it will be beneficial for them to hire you. The higher that you score in any of these areas, the better your chances will be of landing the job you want.

BMCT Question Types

The questions that you will encounter on the BMCT will be randomly generated from an item-banked system. This method allows for each BMCT test administered to be different in terms of questions, but equal in terms of question difficulty. As this is a mechanical exam, you will encounter many different types of questions regarding pulleys and levers, hydraulics, gravity and velocity, gears and belt drives, structures, planes and slopes, etc.

BMCT Sample Questions

Below you will find several BMCT sample questions with answers and answer explanations. Use the free test on this page to further gauge your mechanical aptitude skills for your upcoming exam.

BMCT Sample Question 1 - Velocity

The 101 of physics and the major topic on the BMCT. Acceleration, gravity, and Newton's laws are all common subjects in this section.

Which way is the wagon accelerating? (If either, mark C.)

Bennet Test Practice
Correct Answer
Incorrect Answer
Answer with Explanation

The correct answer is A.

The pendulum is moving backward; therefore, the car is accelerating in the opposite direction. That happens when an object is in an accelerating system, in the same way you feel yourself being pulled backward when the car is speeding up or forward when it is braking.

Remember the physical principle: When an object is within an accelerating system (another object that accelerates or decelerates), the force on the inner object will be in the direction opposite to the acceleration.

BMCT Sample Question 2 - Pullys

With which pulley system would it be easier to lift the load? (If equal, mark C.)

Bennet mechanical test practice
Correct Answer
Incorrect Answer
Answer with Explanation

The required force to lift a weight using a pulley system is distributed evenly to each supporting rope.
The reason for this is that the rope wrapped around the pulley pulls the pulley upwards twice, with each part of the rope. Since the tension is equal along the entire rope, the weight is divided equally between the part of the rope connected to the fixed wheel and the part pulled. Each rope of the pulley system essentially applies some of the load on to the fixed wheel.
The pulley system in A has three supporting ropes; therefore, it reduces the force required to lift the load to one-third.
The pulley system in B has four supporting ropes; therefore, it reduces the force required to lift the load to a quarter.

Remember the physical principle: The more supporting ropes in a pulley system – the less force required.
Note: Only supporting ropes are counted. Ropes that merely change force direction are excluded.

How to Understand Your BMCT II Test Results

Regardless of the different scores shown on your final BMCT score report the employer will receive, there will also be a percentile rating showing where your score falls compared to the normative group.

This percentile rating can tell the employer a lot about you in terms of your skills and if it will be beneficial to hire you. The higher your raw score is once you have completed the assessment, the higher your percentile rating will be.

This percentile placement can be interpreted as follows:

BMCT-II Percentile Score Ranges
0 to 19 Range

This score tells the employer that it would be risky to hire you and that you may take longer to learn the job than someone scoring higher.

This score also tells the employer that you may require closer supervision and that you may never reach the goals so out for you by the company.

20 to 39 Range

This score shows the employer that you have a good grasp of mechanical and physical principles, however, you may still require close supervision while on the job.

This score does give you the ability to still be considered for the role you have applied for only if you are able to demonstrate the desired interpersonal skills during the interview process.

40 to 59 Range

This score demonstrates to the employer that you have a solid understanding of the necessary mechanical and physical concepts and are likely to learn the job being offered at a steady pace.

Falling into this percentile range will have you dubbed as a ‘very good hire’ in the eyes of the recruitment team.

60 to 79 Range

Falling into this percentile group shows the employer that you have an excellent grasp on the mechanical and physical concepts being tested.

It also shows the employer that you will be able to learn your job quickly without too much need for close supervision. Scoring in this range will also have you dubbed as a ‘very good hire’.

80+ Range

Falling into this percentile range shows the employer that you have a very strong, in-depth grasp of the mechanical and physical concepts being tested. Candidates who score in this percentile range will most likely learn the job quickly and will not need much if any supervision once it has been mastered.

This scoring range also shows that you are a fast learner and are likely to pick up on unfamiliar concepts very quickly.
