Our McKinsey Solve Simulation includes all three games from the latest 2025 version and is continuously updated to reflect the structure, difficulty, and logic of the real assessment.

Ecosystem Creation
Practice with Mountain Ridge and Coral Reef scenarios, where you can build over 50 unique ecosystems. There's no single right solution, so you can practice as many times as you like and improve with each attempt.

Redrock Study
Work through four full-length scenarios, each with both study and case sections. The difficulty and themes closely match the actual test, with a strong focus on ecosystem-related reasoning.

Sea Wolf (Ocean Cleanup)
This is the newest addition to the Solve game. Our version is fully dynamic, so you can practice unlimited times and always encounter a different scenario.

We regularly update our simulation to match McKinsey’s latest changes, so you’re always working with the most accurate and relevant version available.

Our McKinsey Solve Simulation has helped hundreds of candidates pass the game with confidence. Since launching our refund campaign on February 2, 2025, only 2% of users have requested a refund after performing below the top 25%. Our simulation prepares you well for the real assessment.

It's also risk-free. If you don’t place in the top 25%, we’ll refund 50% of your initial purchase fee. Just forward us the confirmation email from McKinsey.
