Consulting Math Drills – Short Questions

Practice Package Overview and Instructions This practice package has been developed to provide samples of the actual Math calculations candidates have to perform throughout the Management Consulting Recruiting process including the entrance test (E.g.: McKinsey Problem Solving Test, BCG Potential Test) and case interviews. This package assesses your ability to accurately and quickly calculate business math problems. This practice package contains 300 short math questions. All questions in this package are Short Math questions. Each situation usually has one question and requires one calculation to solve. Remember that of the two criteria (1) accuracy and (2) quickness, accuracy is more important in case interviews. Interviewers would rather allow more time for candidates to perform calculations correctly than get quick but wrong answers. In entrance tests (McKinsey PST or BCG Potential Test), a balanced approach should be targeted. Since the time allowed in those tests are very tight, slowing down to get perfectly accurate answers may not be beneficial. While completing this practice package, do no use any electronic devices (e.g., calculator, computer) when performing calculations to answer the questions. Depending on your purpose of using this package (for Case Interview Prep or for Entrance Test Prep), the appropriate methods for using this package are different. Case Interview Prep: Divide your practice into small hurdles, 5 or 10 questions each. Target 100% accuracy. Any score less than 100% is considered as failed. When you can consistently pass hurdles, try to reduce the time. You may practice calculating out loud as if you are presenting your calculation to interviewers. Entrance Test Prep (McKinsey PST or BCG Potential Test): Divide your practice into small hurdles, 5 or 10 questions each. Only allow yourself 30 – 45 seconds per question (start with 45 then gradually moving down to 30). Then try to increase the number of correct answers within the pre-targeted time allowed. Please let us know if you have any doubts about any question or answer key. Good luck with your studies!
