How different is “consulting math” from high school math?
1. Level of Difficulty
This kind of “consulting math” is more like… elementary math. Most of the time, you will only need to perform additions, subtractions, multiplications, and divisions. In some occasions, there are percentages or fractions. But that’s all about it. No need to worry about all the complicated compound interest, logarithms, derivatives, etc. that once haunted you in high school and college.
The ultimate aim of most consulting projects is to improve business. Therefore math in consulting and in the consulting recruitment process will mostly be on business topics
In most high school and college math, you are allowed to utilize your best friend: the calculator. However, in consulting case interviews and entrance exams (i.e: McKinsey PST, BCG Potential Test), no calculator is allowed. Only your pencil, scratch paper, and your smart brain are allowed.
4. Level of Precision
Unlike science math, consulting math often requires only close-to-correct answers. This comes from the real life difference between the two fields. In science or technology, a tiny margin of error can lead to tragic accidents. But in business, decisions can be effectively and efficiently made based on only near-perfect data/ calculations.
