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.

A live look at our Redrock practice test — the same interface and question style as the real McKinsey assessment.

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.

questions to answer
100%
questions must be answered

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.

Why candidates struggle

1
Information overload. The case report is dense. Candidates who read top-to-bottom run out of time before they reach the questions that matter most.
2
Arithmetic under pressure. Every question must be answered, and there is no room to rely on guesswork. Fast, accurate mental arithmetic — without a calculator — is what separates candidates who score well from those who don’t.
3
Speed-accuracy trade-off. Pacing matters. Most candidates who fail Redrock either rush and make arithmetic errors, or run out of time on the easier later questions.
