McKinsey Solve can change over time, so avoid preparing from a single old walkthrough as if it were permanent. Use your current invitation and McKinsey-provided instructions to confirm the assessment you are actually taking.

Start by understanding the current format you were invited to take. The game has changed over time, so older advice may describe tasks or timing that are no longer relevant.

Practice the underlying skills you can control: reading information efficiently, making clear decisions, tracking variables and staying accurate under time pressure. Avoid over-focusing on unverified scoring rumors.

Use the most current preparation material available and make sure your technical setup is stable. Familiarity with the format is useful, but the goal is sound reasoning rather than memorizing a sequence. For more detail, see the McKinsey Solve guide.

Has anyone seen an invite that gives only the word "Solve" but does not specify the games? I would not want to prep for an old version.

If the invite only says Solve and gives no game details, what is the safest prep approach?
