Hi, what's the best way to prepare for this test? It's 20 mins, 30 qns.

Also does anyone know what the cutoff score usually is for this?

Hi Anonymous,

when I prepared for it some years ago, I mainly focused on the GMAT, paying a lot of attention to the time constraint.

Topics of the test include:

  • Probability
  • Permutations
  • Percentages
  • Geometry
  • Ratios

The questions are not super hard once you have understood the general logic. The most difficult thing – where many people fail – is the time management. You can find some sample questions at the link below:

As you pointed out, the test is 30 questions in 20 minutes, which means that you have less than one minute per question. Together with the fact that you get penalized for wrong answers, this implies that you should leave blank some questions initially. If you don’t do this you won’t manage to obtain a good performance.

When I did mine, I covered 23-24 questions, skipping 6-7. As I finished with a couple of minutes left, I went back to the previous questions, managing to complete 2-3 additional ones.

Hope this helps,

Agree with Francesco. Several points on my side:

  1. The best way is to go through GMAT Official Guide, concentrating on Math Part. Manhattan guide will give you the right math theory and topics.
  2. Learn Fast Math:
  • Learn how to multiply double digit numbers fast (
  • Learn the division table up to 1/11 (i.e. 5/6 = 83.3)
  • Learn how to work with zeros (Hint: 4000000 = 4*10ˆ6)
  • Use math tools (Mimir math for iOS), Math tool on Viktor Cheng website to practice

I have seen different cases, I remember colleagues who got an offer with a score of 12. Honestly, the best way to prepare is to find forums online where people share past questions. Best way to practice with questions that were actually asked instead of spending weeks with GMAT/GRE prep.

it depends on the geography whether or not Oliver Wyman uses a numerical reasoning test.

In Germany, there is no numerical reasoning test anymore. Nevertheless, you should obviously still do your homework when it comes to your math skills for the life interview!

Best regards
