Sustainable Future Lab — independent McKinsey Solve practice
Try a free 6-minute SFL sample: rank priorities and make branching decisions. Original CaseStar practice inspired by candidate reports, with trade-off review.
What can I practise in the free Sustainable Future Lab sample?
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.
Is this official?
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.
How is it scored here?
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.
Does my practice score predict the real assessment result?
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.
Can I use CaseStar or other tools during the real Solve assessment?
No. Practise beforehand, then close CaseStar and other preparation tools. McKinsey’s published integrity rules prohibit outside assistance and 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. Sustainable Future Lab is described in candidate reports, not named on McKinsey's public Solve page. These are original practice scenarios with CaseStar-model feedback. Follow your own invitation for the real assessment's tasks and timing.
