Engineered for precision — so real exams feel routine.
Infinite MBB-Level Business Cases
Gemini AI generates a never-repeating stream of Fermi estimates, M&A Go/No-Go decisions, profitability turnarounds, and VC pitches — the exact case types that land offers at McKinsey, Bain, and BCG.
Authentic Executive Pressure
3 minutes of enforced preparation. Then a cold Q&A that hunts every gap in your MECE structure. No comfort, no hints — the same pressure as a senior partner who has already decided you’re wasting their time.
C2-Level & Structural Feedback
Not a grammar check. A named logic tree showing the exact framework you should have applied — Revenue × Volume vs. Price, MECE cost drivers, market sizing funnels. Plus forced vocabulary upgrades to C1/C2 executive register.
An AI partner that never flatters you, never reschedules, and never runs out of cases. Unlimited high-stakes sessions — available 24 / 7, at a fraction of the cost of a human coach.
