Diagrammatic Reasoning Tests

Diagrammatic reasoning tests are all about applying logic to a series of different flow charts or diagrams.

  • What are diagrammatic reasoning tests?

    Diagrammatic reasoning tests are potentially unlike any test you’ve taken before. Using a series of shapes, patterns or diagrams, each question will ask you to use logic to work out what it is that connects the pattern in front of you.

    The test is timed, meaning you won’t have long to work it out. Logical thinking is a skill that’s useful for jobs across a huge range of sectors, from the armed forces to the world of law. The best way you can prepare for a test of this kind is to practice as many online papers as you can.

  • What is the diagrammatic reasoning test format?

    Diagrammatic reasoning tests are designed to evaluate a person's ability to solve problems using visual information. These tests present a series of diagrams, images, or shapes that follow a certain pattern or sequence. The goal is to identify the underlying rule or pattern and use it to predict what comes next in the series or to complete a missing part of the diagram.

    The format of diagrammatic reasoning tests can vary depending on the test provider, but generally, they involve multiple-choice questions where the test-taker has to select the option that fits the pattern or completes the diagram. Some tests may also require the test-taker to identify which option doesn't fit the pattern or complete the diagram.

  • What skills do diagrammatic reasoning tests assess?

    Diagrammatic reasoning tests are used to examine an individual's ability to think logically under pressure. In the army, these are vital skills you’ll have to utilize on a day-to-day basis, which explains why these tests are increasingly being used as part of the recruitment process for the armed forces.

    These tests typically present a series of diagrams, images, or shapes that follow a certain pattern or sequence, and the test-taker is required to identify the underlying rule or pattern and use it to predict what comes next in the series or to complete a missing part of the diagram.

  • What types of questions are on diagrammatic reasoning tests?

    Diagrammatic reasoning tests typically present a series of diagrams, images, or shapes that follow a certain pattern or sequence. The types of questions that can be asked on these tests can vary depending on the test provider, but generally fall into one of the following categories:

    • Completion questions: In this type of question, the test-taker is presented with a sequence of diagrams, with one or more missing parts, and is asked to select the option that completes the sequence. The test-taker must be able to identify the underlying pattern or rule and use it to predict what comes next in the series.
    • Selection questions: In this type of question, the test-taker is presented with a sequence of diagrams, one of which is different from the others. The test-taker must identify the diagram that doesn't fit the pattern or sequence and select the corresponding option. This type of question assesses the test-takers ability to recognize patterns and relationships between shapes and symbols.

    Overall, diagrammatic reasoning tests require the test-taker to analyze and interpret visual information quickly and accurately, and use pattern recognition, logical reasoning, and problem-solving skills to arrive at the correct solution.

  • Why do military organizations use diagrammatic reasoning tests in their Recruitment?

    Military organizations require personnel with strong problem-solving and critical thinking skills, as well as the ability to make quick decisions based on limited information. Diagrammatic reasoning tests are an effective way to assess these cognitive abilities in potential recruits.

    These tests can evaluate a candidate's ability to interpret and analyze visual information, recognize patterns, and use logical reasoning to arrive at the correct solution. This can help military organizations identify candidates who are likely to excel in roles that require these skills, such as pilots, engineers, and analysts.

    Diagrammatic reasoning tests are also useful for military organizations because they are not language-dependent. This means that candidates from different cultural and linguistic backgrounds can be evaluated using the same test. This is particularly important for military organizations that operate in multinational environments, where personnel from different countries must work together effectively.

  • How To Prepare and Pass Your Diagrammatic Reasoning Test

    Here are 5 tips on how to prepare and pass your diagrammatic reasoning test:

    Practice with sample tests

    To improve your skills and confidence, it is important to practice with sample diagrammatic reasoning tests. These can be found online or in test preparation books. This will help you become familiar with the format of the test, and the types of questions that will be asked.

    Learn the different types of patterns

    Diagrammatic reasoning tests often involve recognizing different types of patterns, such as rotation, reflection, and symmetry. It is important to become familiar with these patterns, as they will help you identify the underlying rule or pattern in the diagrams.

    Manage your time

    Diagrammatic reasoning tests are often timed, so it is important to manage your time effectively. Read the instructions carefully and work through each question methodically. Don't spend too much time on any one question, and make sure you have attempted all questions before the time runs out.

    Focus on accuracy

    Accuracy is more important than speed in diagrammatic reasoning tests. Take the time to carefully analyze each diagram and select the option that fits the pattern or completes the diagram. Don't rush through the questions, as this may lead to errors.

    Stay calm and focused

    Diagrammatic reasoning tests can be challenging, but it is important to stay calm and focused throughout the test. Take deep breaths and try to relax. Remember that you have practiced and prepared for this test, and that you are capable of doing well. Stay focused on the task at hand and do your best.

Diagrammatic Reasoning Tests Tips

Understand the Patterns

Getting a grip on pattern recognition is crucial for success in Diagrammatic Reasoning tests. As you practice, focus on identifying how shapes, arrows, or other elements in the diagrams change. Is there a rotation? Do shapes increase or decrease in size? Recognizing these patterns will help you predict what comes next in the sequence.

Keep Calm and Logically Reason

Logical reasoning is the heart of Diagrammatic Reasoning tests. Don't let complex diagrams intimidate you. Stay calm, and remember that each element is logically connected. Break down the flowcharts into smaller components if needed and approach each step methodically. With a clear head, the logical flow will become apparent.

Manage Your Time Wisely

Time management can make or break your performance. While it's important to work quickly, accuracy is key. Consider spending a few seconds to understand each question before diving in. As you practice, keep track of the time it takes you to answer questions correctly so you can pace yourself during the real test.

Rule Out Incorrect Answers

When in doubt, use the process of elimination. If an answer doesn't align with the rule set you've inferred, it's probably incorrect. Narrowing down your choices can significantly increase your chances of selecting the right answer, especially when you're stuck between multiple options.
