Case Interview Math Mastery Course

Case math the way it comes up in a consulting interview

This course teaches the math consulting interviews actually test. That means setting up a calculation from a business question, getting to the number quickly and accurately, and saying what the result means for the client. It has 29 video lessons (4+ hours) and 40+ hours of practice with worked solutions.

What’s inside

• 29 video lessons in five parts: the role of math in cases and how it’s scored, a 7-step approach to case math, typical problem types and the formulas behind them, calculation speed and accuracy (fractions, percentages, rates, probabilities, large numbers, and estimation), and market sizing at basic and advanced levels
• Six guided live practice lessons that solve case math problems step by step
• 2,000+ calculation drills across difficulty levels
• 100 business problems, 29 chart-based questions, and 24 full case math problems, each with a worked solution

How to work through it

1. Watch the two free Start Here lessons, then Setting the Stage and the 7-step approach. The rest of the course builds on that approach.
2. In the guided live practice lessons, pause and do the calculation yourself before you watch the solution.
3. Work through the fast-math lessons alongside the calculation drills. Short, regular drill sessions build speed better than occasional long ones.
4. Move on to the business problems, chart questions, and full cases once your drill speed is steady. Say each answer out loud the way you would to an interviewer: first the result, then what it means.
