About the McKinsey Solve
Solve is a set of game-like tasks, not a question paper. Each task has its own interface.
On DrillCaseDrillCase has scenarios for Redrock Study, Sea Wolf, Sustainable Futures Lab and Ecosystem Creation.
Redrock asks you to collect data, calculate and write a short report under time pressure.
On DrillCaseRedrock-style scenarios include exhibits, a research journal and a built-in calculator.
Learning a task's controls on test day costs time you need for the analysis.
On DrillCaseRun the tasks back to back from one launcher, as many times as you like.
