Oliver Wyman Numerical Reasoning + Competency Test

Hi! I was wondering if you have an exhaustive list of all of the resources that would be available for me to prepare for the OW Numerical + Competency Test. I heard it is similar to GMAT, but was wondering if PrepLounge has any prepared materials that I can use, I would also appreciate any list of any other websites as well. Thanks so much!

hey there! 

the OW test is indeed somewhat GMAT-style, especially the numerical part, with a mix of math, logic, and reading comprehension. 

  • While PrepLounge is primarily case-focused, you can still use:
    • The “Case Math” section: quick mental math drills
    • Market sizing practice
    • Community Q&A for tips on OW test structure and recent experiences

other resources I recommend

  1. JobTestPrep – Offers tailored Oliver Wyman-style practice packs (numerical + verbal + situational judgment)
  2. AssessmentDay – Great for SHL-style numerical reasoning, which is similar to OW’s format
  3. Practice Aptitude Tests (by Graduates First) – Free and paid tests for numerical, logical, and verbal reasoning
  4. GMAT Club (Quant Section) – Use it for math-heavy practice
  5. MConsultingPrep – Has a paid section for general aptitude prep and test-taking tips
  6. Talent Q / Korn Ferry-style tests – Sometimes relevant for OW's psychometric components

What I would Practice Specifically

  • Interpreting tables, charts, and graphs quickly
  • Ratio, percentage, and data sufficiency questions
  • Time management — you often get ~60 seconds per question
  • For the competency part: prep structured answers to common behavioral questions (e.g., teamwork, problem-solving, leadership)

Hope that helps!
