Watson Glaser Test: Full Course Preparation (2026)
Last updated: 30 September 2026 | Trusted by thousands worldwide.
The Watson Glaser test is widely considered one of the most challenging employment assessments, with its unique rules and counterintuitive solving methods. It's a timed psychometric test used extensively by law firms and government legal services to evaluate candidates across several core critical thinking skills.
Our experts have developed an adaptive Watson Glaser PrepPack that starts with a diagnostic assessment of your level, then adjusts as you practise to close your specific gaps. It includes realistic practice simulations that reflect the actual test's structure and timing, as well as interactive study guides for each of the five skill areas with detailed explanations that reveal the logic behind each answer.
Our PrepPack is the most comprehensive product on the market, trusted by top law schools and universities in the UK, including Oxford University and Cambridge University!

Inside Our Watson Glaser Test PrepPack
Our Watson Glaser Test PrepPack is built entirely around one adaptive learning system. As you work through the course, it learns from your performance and continually adjusts your practice to your progress, strengths, and weaknesses.
- 1 Watson Glaser Diagnostic Test: Start with a diagnostic assessment covering every question type to identify your strengths, weaknesses, and key opportunities for improvement.
- Over 600 Adaptive Practice Questions & Test Simulations: Work through personalised practice drawn from our extensive question bank. The system adapts your practice to reinforce the areas you're already strong in, target weaker areas, and help improve your overall Watson Glaser performance. You'll complete both section-specific practice tests and full simulations designed to replicate the timing, format, and content of the real test.
- Personalised Feedback: As you practise, the system learns from your performance and provides tailored feedback and support, helping you understand where you can improve and what to focus on next.
- 5 In-Depth Study Guides: Build a strong understanding of the theory behind each section, with interactive guides covering the techniques and strategies you can use to approach each question type.
Every one of these adapts as you go, which is really what sets this apart from a fixed set of practice tests you work through once.
Generic practice questions, or asking a general AI chatbot to quiz you, can help you get a feel for the test, but neither can replicate its exact timing and format, adapt to your specific weak spots, or tell you how you genuinely compare to everyone else sitting the same exam.
Our adaptive system is built to do exactly that.
Our adaptive system works for you:
- Practise, and get it wrong safely: Answer something wrong, and you can retry it on the spot with a detailed explanation, so the gap actually closes before you move on.
- See where you actually stand: After every session, a report shows your progress, the difficulty level you reached, and clear objectives for next time. You'll also get a Relative Score, a percentile showing exactly how you compare to other candidates preparing for the same test, not just your raw right-vs-wrong count.
- Build toward your actual test date: Enter your test date, and the system builds a study plan around it, shifting toward full-length, timed simulations as the day approaches.
Together, this means your practice time is always going toward whatever will move your score next, not just repeating what you've already mastered.
Take a look inside:
The Watson Glaser is genuinely difficult, not because it demands specialist knowledge, but because it challenges intuition with subtle reasoning and counterintuitive rules that catch even well-prepared candidates off guard.
Our practice questions are deliberately built to expose those traps, so by test day, you'll spot them instantly instead of falling for them.
Here's what that's meant for people who've already used it:

And these are just three examples, across two of the five sections you'll face on test day. The PrepPack walks you through every trap like this, across all five, so nothing catches you off guard when it counts.

Watson Glaser Test FAQs
The Watson Glaser test assesses five critical thinking skills, namely logical reasoning (Inferences), critical judgement (Assumptions), logical-based reasoning (Deduction), analytical reasoning (Interpretation), and argument evaluation (Evaluation of Arguments).
Each section has its own rules and question format, and success requires mastering all five. Candidates cannot compensate for weakness in one area by performing strongly in others. Head to our Watson Glaser test guide page to learn more about the test structure, scoring, and more.
The Watson Glaser Critical Thinking Appraisal is considered to be one of the hardest pre-employment tests on the market today, due to its unique and counterintuitive set of rules, as well as its focus solely on critical thinking.
A good score is generally 33 - 34 correct answers out of 40, placing candidates at around the 80th percentile, the benchmark typically required for competitive roles such as training contracts at top law firms. Scores are assessed relative to other test takers, so the more applicants competing for a role, the higher the score needed to progress.
