Try a free 10-minute Sea Wolf practice site. Compare microbes, check traits and build a treatment, then explore timed McKinsey Solve-style practice. The interactive controls will appear once your saved-session check finishes.
The free Sea Wolf sample gives you one site and a 10-minute clock. Inspect the site requirements, compare microbes and submit a three-microbe treatment. The full CaseStar practice run covers three sites in 30 minutes.
No. It is an independent practice simulator based on public information about McKinsey Solve and gamified problem-solving assessments.
Exam mode hides live hints, live efficiency scoring, seed controls, and solution feedback until review so the session feels closer to a proctored assessment.
Read a site’s requirements, compare the available microbes and confirm a three-microbe treatment. Check the team’s numerical attributes and traits against the complete brief. The free sample covers one site; the full practice run covers three. Feedback follows CaseStar’s practice model, not an official McKinsey score.
No. Feedback uses CaseStar’s practice model. It helps you review your decisions and identify skills to practise; it is not McKinsey’s scoring formula or a prediction that you will pass.
No. Practise beforehand, then close CaseStar and other preparation tools. McKinsey’s published integrity rules prohibit outside assistance, AI tools, pre-prepared notes and recording or screenshots during Solve, except for accommodations approved by McKinsey. Follow your invitation and the current official rules.
Casestar is not affiliated with McKinsey. Official public sources describe Solve broadly; this is independent Solve-style practice with directional feedback, not a clone of McKinsey's platform.
