Watson–Glaser guide

One free sitting · Two ways to prepare

Watson–Glaser practice: build your critical reasoning.

Build accuracy without a time limit, or practise working under a 30-minute deadline. Every question includes a free worked explanation after you finish.

Each section has five questions: two standard and three stretch. Read closely, revisit questions and change answers freely before finishing. Skipped questions earn no points, with no extra penalty.

Both modes include 60% stretch questions. The labels describe our intended challenge; they are not yet calibrated to candidate results or official scores.

Your result includes a raw score, a section breakdown and all explanations. Optional confidence ratings help you compare certainty with accuracy. This independent practice does not provide an official norm, pass mark or prediction of employer performance. Game Assessment Prep is not affiliated with Pearson.

Leaving or refreshing ends unfinished untimed practice. This browser remembers previously selected question IDs to reduce repeats. The finite bank will eventually repeat; clearing browser data also clears that memory.

Read the five section rules

Take as long as you need before starting. The sections use different standards of proof.

  1. 1
    Inference5 questions

    How to answer: Inference

    Treat the passage as true. Judge how well it supports the proposed inference. True or False requires confidence beyond reasonable doubt; Probably True or Probably False means the evidence favours that judgment. Choose Insufficient Data when you cannot make a supported judgment either way. Ordinary everyday knowledge may help, but do not invent missing facts.

    Answer meanings
    1. True:
    The information establishes the statement beyond reasonable doubt.
    2. Probably True:
    The statement is more likely true than false, but is not established.
    3. Insufficient Data:
    There is not enough information to judge which is more likely.
    4. Probably False:
    The statement is more likely false than true, but is not disproved.
    5. False:
    The statement contradicts, or is ruled out by, the information.
  2. 2
    Recognising assumptions5 questions

    How to answer: Recognising assumptions

    Decide whether the speaker takes the proposed assumption for granted in making the statement. An assumption can be unstated and need not be justified. A related belief or a possible explanation is not enough: consider the bridge the speaker relies on.

    Answer meanings
    1. Assumption Made:
    The reasoning takes this for granted, even though it is not stated.
    2. Assumption Not Made:
    The reasoning does not need to take this for granted.
  3. 3
    Deduction5 questions

    How to answer: Deduction

    Accept every premise as true. The conclusion follows only if it must be true under those premises, with no additional facts. If even one situation consistent with the premises makes the conclusion false, it does not follow. “Some” means at least one and can include all.

    Answer meanings
    1. Conclusion Follows:
    The conclusion necessarily follows: it must be true if all the premises are true.
    2. Conclusion Does Not Follow:
    The conclusion need not be true, even if all the premises are true.
  4. 4
    Interpretation5 questions

    How to answer: Interpretation

    Accept the information in the passage. Decide whether the evidence establishes the conclusion beyond reasonable doubt. This section does not require the strict logical necessity used in Deduction, but a merely plausible explanation is not enough. Avoid unsupported causes and generalisations.

    Answer meanings
    1. Conclusion Follows:
    The conclusion follows beyond reasonable doubt from the information.
    2. Conclusion Does Not Follow:
    The information leaves reasonable doubt about the conclusion.
  5. 5
    Evaluating arguments5 questions

    How to answer: Evaluating arguments

    Assume the facts asserted by this argument are true. Judge it on its own: a strong argument gives an important, directly relevant reason supporting the position it takes (Yes or No). A weak argument misses the issue, gives a reason of little importance, or fails to support its stated position. Set aside your own opinion and do not invent opposing arguments.

    Answer meanings
    1. Strong Argument:
    The reason is important, directly relevant, and supports the position the argument takes.
    2. Weak Argument:
    The reason lacks importance or direct relevance, or does not support the position the argument takes.

Instructions remain available throughout. The 25-question practice gives equal attention to all five sections.
