Redrock Study Task
The data-heavy first scenario of the 2026 McKinsey Solve assessment. Read a structured report, answer math-style questions, and watch the clock — fast, accurate arithmetic is everything.
What is the Redrock Study Task?
Redrock is the first scenario in the McKinsey Problem Solving Game. It’s the most quantitative module in the assessment: candidates are given a structured business report with embedded data tables, then asked to answer a sequence of math-style questions that depend entirely on parsing the report correctly.
If you took the legacy McKinsey Problem Solving Test (PST), the format will feel familiar. The difference is that Redrock is delivered inside a timed, interactive interface — meaning navigation speed and reading efficiency matter as much as the underlying maths.
Format & timing
Every question must be answered — there is no option to skip. With around three minutes per question and no lifelines, fast and accurate arithmetic is the core skill Redrock tests. Slowing down costs you time on later questions; rushing creates errors that cost you points.
