Math practice for consulting is a must. All management consulting roles require a comfort with statistics, quantitative data, and data-based facts and recommendations. Since management consultants spend so much time working with numbers, analyses, charts, calculations and other math work, you will be tested on your mental math skills!

What Math Do I Need?

The written and mental math needed for consulting applications and case interview math examples will include:

  • Standard math, such as fractions, divisions, multiplication, percentage and other basic concepts. The math you encounter will involve business contexts, but accuracy and speed matter. Consulting case interviews do not permit the use of calculators, however. This is why practice is crucial!
  • Word problems. These may be similar to the word-based problems you encountered on the GMAT and other standardized tests. These may or may not include a business-based context.
  • Mental math, requiring you to do math on the fly. Often one of the most challenging components of the interview for candidates, this requires you to be able to answer math questions quickly and spontaneously, without turning to paper and pen.
  • Full-case questions. In these cases, you will be asked to review a more complex example with multiple types of data, and to answer different business math questions based on the one example.
  • Questions based on charts. You will be given charts or data in different forms and be asked to interpret the data.

Who is it for?

Mental Math for Consulting is for everyone who dreams of working at a consulting firm, but may be too scared of consulting math.

Mental Math for Consulting is for the talented student who wants to ace their case interviews but hasn’t exercised her mental math muscles since grade school.

As a consultant, numbers are your life. Whether it’s conducting market research, calculating ROI or figuring out weighted averages, you’re gonna be swimming in numbers.

Because of that, consulting firms want to know you can handle numbers with the best of them.

That’s why no consulting firm will let you use a calculator in your interview.

Mental Math for Consulting is for everyone who wants to let their interviewers know they have the quant skills to ace consulting math and make it as a top-performer.

How will it help?

When consulting firms are interviewing you, they’re trying to see if you have a grasp of the principles you’ll be using day in and day out as a consultant.

For most of you, once you got handed a calculator in grade school, you stopped using your brain to figure these problems out, which puts you at a huge disadvantage in consulting interviews.

Mental Math for Consulting will put you back in control as you get ready for your consulting interviews by catching you up on the years of mental math training you’ve missed.

Upon finishing you will know how to:

Deal with any math problem your interviewer puts before you.

ROI? Got it.

Weighted averages? Covered.

Breakeven point? That too.

And more.
