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."

  • Three scenario modules (~75 min total)
  • Personal debrief explaining your decisions
  • Single comparable score (SAR)
  • Lifetime access to all beta updates
STRATAGEM Cascade Ridge — habitat map and species roster
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

Cascade Ridge — design a watershed that doesn't collapse

Twenty-four species, four habitat zones, a 60-tick horizon. Probe what you can't see, pick a viable roster, and stake your predictions before drought, fire and invasives hit.

  • Systems thinking
  • Long-horizon prediction
  • Adaptation under change

Module 2 · Wildfire

Brief, investigate, then commit your forces

Read incomplete intelligence under time pressure, weigh contradictory evidence, commit to a hypothesis, and allocate crews across the basin before conditions shift.

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

Module 3 · Sustainable Futures

Read the room, rank the priorities, decide under ambiguity

A 20-minute behavioural scenario: read a sustainability mission briefing, rank the team's opening priorities, then work through ~12 branching decisions where each choice reshapes what the team faces next. No numbers, no calculator — pure judgement.

  • Prioritisation under ambiguity
  • Stakeholder & team judgement
  • Consistency of decision philosophy

Cards, sliders, allocation — not multiple choice

Every stage is a real decision surface. Here's what you'll actually be using.

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.
