What’s Included in the Simulation
As of May 2026, our McKinsey Solve simulation reflects the latest version of the assessment and covers all current game types.
Sustainable Futures Lab (Newest Game)
Our Sustainable Futures Lab simulation includes 10 full scenarios, each with 13 questions that closely match the structure and style of the real test. After each attempt, you’ll receive a detailed report showing how your answers map across the key traits McKinsey evaluates, along with question-by-question feedback to help you improve your score next time.
Redrock Study (2026 Current Version)
Work through 10 full-length scenarios, each combining study and case sections. The format and difficulty closely reflect the real assessment, with a strong focus on ecosystem-related reasoning and data interpretation.
Sea Wolf (2026 Current Version)
Our Sea Wolf simulation is dynamic, so you can practice as many times as you want and get a different scenario each time. It’s designed to help you get comfortable making decisions under uncertainty and navigating the format of this part of the test.
Ecosystem Creation (Bonus Practice)
Fully dynamic, with species’ calories needed and provided, food sources, and predator relationships changing each time you play. It gives you access to an unlimited number of unique scenarios. While no longer part of the official McKinsey Solve, it remains in our simulation in case McKinsey reintroduces this game.
Why Candidates Trust Our Simulation
Our McKinsey Solve simulation has helped over 1,000 candidates prepare for the assessment with confidence.
Since launching our refund campaign in February 2025, only 3% of users have requested a refund after completing the simulation. This reflects how closely our practice matches the real assessment and how well it prepares you for it.
