The free Sustainable Future Lab sample takes about six minutes: rank four priorities and make three decisions. The full CaseStar scenario has one ranking and twelve branching decisions on a 20-minute clock. This format is informed by candidate reports, not official confirmation of a named McKinsey module.

No. McKinsey's public Solve page describes the assessment broadly and does not name this module. Candidate reports inform our practice format; invitation duration alone does not establish which tasks you will receive.

McKinsey has not published a scoring model. Casestar scores your priority ranking, the trade-off quality of each branching decision, and how consistently you weigh the same trade-offs across the session — clearly labeled as Casestar's model.

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.
