Tip 1: Find Out if the Numerical Reasoning Test Is Part of Your Selection Process
Depending on the location you are applying to, you may not need to take the Numerical Reasoning Test at Oliver Wyman. Before investing valuable time that could be spent preparing for your case interviews, check with your local HR contact to confirm whether the Numerical Reasoning Test is part of your selection process. If it is, then it's time to start preparing – this test is pretty tough!
Tip 2: Refresh Your Math Skills
It’s likely been a while since your last math exam, so you should review the following topics that might appear in the Oliver Wyman Numerical Reasoning Test:
- Algebra
- Ratios
- Percentages
- Geometry
- Probability
- Permutation
- Combinatorics
Make sure you're comfortable with key formulas, such as those for diameter, volume, or area of geometric shapes. A formula sheet can be helpful, but you should be able to find and apply formulas quickly. While you can use a calculator, practicing mental math will be useful, especially since you won’t be allowed a calculator in the case interviews. The sooner you start practicing, the better!
Tip 3: Choose Your Preparation Materials Carefully
Oliver Wyman does not provide official sample questions for the Numerical Reasoning Test. Therefore, we recommend practicing with GMAT-style questions. These resemble the types of questions on the Numerical Reasoning Test and can be found for free online. Additionally, there’s little specific preparation material for the Oliver Wyman math test (at least in Europe).
Tip 4: Ask Former Candidates for Advice
Do you know anyone who has already gone through the Oliver Wyman application process? Ask them if they remember any specific test questions! Even if they don’t remember the exact questions, they can give you an idea of what the test is like and what to watch out for. This will help you prepare more efficiently by learning from others’ experiences. If you don’t know anyone, use online forums like our Consulting Q&A, where you can find candidates and experts with Oliver Wyman experience who can assist you!
Tip 5: Practice the Numerical Reasoning Test Under Real Exam Conditions
When you begin with a practice test, simulate real exam conditions: set a timer for 20 minutes and try to answer as many questions as possible. Spend no more than one minute per question, and only look at the solution steps once you've completed the test. This way, you can calculate your total score and see which questions give you trouble. Focus on these areas and do more exercises on those topics. If you have weaker areas, don’t stress too much. Over time, you’ll get familiar with the different question types and know which ones to skip.
Tip 6: Eliminate Distractions
Find a location where you feel comfortable and won’t be disturbed for the test! The library may seem quiet, but you could be distracted. Your home is probably a better choice. If you live in a shared apartment, ask your roommates not to disturb you for 20 minutes. Turn off your smartphone and any social media notifications. Full concentration is required!
Also, check if your internet connection is stable. Slow loading times can cost you valuable time – and it would be frustrating to fail because of this!
Tip 7: Skip Difficult Questions
It’s nearly impossible to complete the entire test in the short time available. So don’t try to solve every single question! Work through the test and skip questions you don’t know the answer to right away. If you have time left at the end, try to answer them.
Since this test penalizes for wrong answers, only guess if you’re sure you can eliminate at least one option.
Tip 8: Don’t Forget the Bigger Picture
The Oliver Wyman Numerical Reasoning Test is one of the most challenging selection tests. But it makes up just a small part of the entire application process. Of course, you should prepare well, but the personal fit and case interview rounds are far more decisive for your offer. Plan your preparation time wisely and don’t spend too much time on the online test.
