Beta · McKinsey Solve preparation

Practice complex reasoning assessments — and actually understand why your decisions worked.

STRATAGEM is the closest thing to practising McKinsey Solve, with one difference: every debrief explains the chain of consequences your decisions set off, not just whether you got the answer "right."

  • Two scenario modules (~60 min total)
  • Personal debrief explaining your decisions
  • Single comparable score (SAR)
  • Lifetime access to all beta updates

Why STRATAGEM

Not another aptitude quiz.

Most reasoning tests grade you with a percentile and leave. STRATAGEM puts you inside scenarios that behave like real systems — and explains every cascade your decisions set off.

Scenarios, not questions

Investigate, hypothesise, allocate, and watch what plays out. No multiple choice. No timer pressure tricks.

Causal debriefs

Every outcome is reconstructed as a chain: your decision → consequence → secondary effect → final outcome.

One comparable score

The Strategic Aptitude Rating — rolled up from outcome quality, information efficiency, decisions, and risk.

Module 1 · Ecosystem

Design a habitat that doesn't collapse

Pick species for three habitat zones, predict cascades before they happen, and adapt as the simulation runs for 60 ticks of forecast shocks and invasives.

  • Systems thinking
  • Long-horizon prediction
  • Adaptation under change
STRATAGEM Ecosystem — habitat zones with species selection
Module 2 · Wildfire

Brief, investigate, then commit your forces

Read incomplete intelligence under time pressure, weigh contradictory evidence, and allocate personnel and equipment before the wind shifts.

  • Evidence evaluation
  • Triage under uncertainty
  • Decision-making with imperfect information

Module 2 · Investigation

See exactly why you scored what you scored

Every debrief walks the causal chain — the wolf you didn't protect, the browsing pressure that followed, the aspen die-off, the score you ended up with. You learn the system, not the test.

  • Counterfactual reasoning
  • Causal chain walkthrough
  • Personalised strengths and gaps

Sample report

What you walk away with

A single SAR score, four axis scores, your strongest and weakest moves, and a causal walkthrough of the cascade you set off.

Causal chain — counterfactual

Protecting Wolf at tick 30 would likely have prevented the keystone collapse. Deer browsing pressure would have remained lower, Aspen regeneration would have held, and the late-stage cascade would not have removed Beaver from the wetland — projected SAR +18.
