Which McKinsey Solve Prep Tools Match the Real Test?

Part ofConsulting Online Assessments: Which Test Will McKinsey, BCG or Bain Send You?

McKinsey Solve (formerly the Problem Solving Game) is a gamified online assessment used by McKinsey & Company. Preparing for it requires tools that simulate the specific mini-games — Redrock data analysis, ecosystem management, and systems thinking scenarios — rather than generic case interview practice.

The challenge for candidates is that most "McKinsey prep" materials focus on live case interviews, not the digital assessment that comes first. Solve is the gate — if you do not pass it, you never reach the case interview stage. This guide compares the available McKinsey Solve prep tools honestly, including where DrillCase fits and where other options may serve you better.

What Makes Good McKinsey Solve Prep?

Not all preparation is equal. The McKinsey Solve assessment uses a specific format that generic case prep does not address. Based on candidate reports and the current Solve format, effective prep tools must meet three criteria:

• Must simulate actual game formats: Solve uses interactive simulations — Redrock data analysis, ecosystem management, and pattern recognition games. A tool that only offers case interview questions does not prepare you for the digital assessment interface, the game mechanics, or the specific cognitive skills each mini-game tests.
• Must include data analysis scenarios: The Redrock mini-game and related exercises test your ability to interpret data exhibits, identify patterns in visual information, and make decisions from quantitative evidence. Prep without data analysis practice leaves you unprepared for a core component.
• Must have timed format matching the real test: McKinsey Solve is approximately 60-70 minutes with strict time limits per simulation. Untimed practice builds false confidence — the time pressure changes how you process information and make decisions.

McKinsey Solve Prep Options Compared

We evaluated the major categories of McKinsey Solve preparation against these three criteria. This comparison reflects what each option actually provides as of mid-2026 — we have not fabricated features for any competitor.

Generic Case Prep Sites

Platforms like PrepLounge, CaseCoach, and similar services focus on traditional case interview preparation — structuring business problems, practicing with peers or coaches, and learning consulting frameworks. This preparation is valuable for the interview stage but does not simulate the Solve assessment format. Candidates who rely exclusively on case prep for Solve are preparing for the wrong test.

YouTube and Free Walkthroughs

Several creators offer Solve walkthrough videos explaining the game mechanics and general strategies. These are genuinely helpful for understanding what to expect, and we recommend watching them as a starting point. The limitation is that watching is passive — you do not build the timed decision-making skills that come from active practice under time pressure.

Private Coaching

One-on-one coaching can be excellent if your coach has direct experience with the current Solve format. The challenge is verification — Solve changes regularly (Redrock became standard in 2026), and not all coaches stay current with format updates. At $200+ per hour, the cost is significant, and the value depends entirely on your specific coach's knowledge of the current assessment.

Official McKinsey Practice

McKinsey provides one sample scenario on their website. It is authentic by definition — it comes from McKinsey — but one scenario is insufficient for building the pattern recognition and time management skills that come from repeated practice. Use it as a benchmark, not as your entire preparation.

DrillCase McKinsey Solve Coverage

DrillCase covers McKinsey Solve preparation through our McKinsey Solve simulator and dedicated Solve practice modules. Here is what the platform includes:

Redrock-Style Data Analysis Scenarios

Practice scenarios that test the same cognitive skills as Redrock: pattern recognition in visual data, spatial reasoning, and decision-making with incomplete information. Scenarios are timed to match Solve's pacing and revised when candidates report format changes.

Ecosystem Simulations

Systems thinking exercises that mirror the Ecosystem Game's format: build sustainable systems under environmental constraints, balance interdependent variables, and manage trade-offs between competing objectives. The 2026 scenarios include expanded variables reflecting McKinsey's updated Ecosystem Game complexity.

Data Analysis Modules

Standalone data interpretation practice covering chart reading, trend identification, and quantitative reasoning — the foundational skills that underpin every Solve mini-game. These modules work as both Solve prep and general analytical skill building. Try our free chart interpretation drills to experience the question quality.

Format Updates

DrillCase revises its McKinsey Solve content when candidates report format changes. When McKinsey changes the assessment format — as they did by making Redrock standard in 2026 — we update the practice scenarios to match. Your preparation materials should not be older than the assessment format they claim to prepare you for.

Our Recommendation

There is no single tool that perfectly replicates the McKinsey Solve experience — McKinsey's proprietary game format makes exact duplication impossible for any third party. The best preparation combines multiple resources:

• Start free: Watch YouTube walkthroughs to understand the format. Complete McKinsey's official sample scenario. Use DrillCase's free chart interpretation and mental math drills to build foundational data skills.
• Invest in format-specific practice: DrillCase's Solve practice modules provide the timed, interactive practice that passive resources cannot. 20+ scenarios give you the repetition needed to build pattern recognition.
• Consider coaching selectively: If your budget allows, 1-2 sessions with a coach who knows the current Solve format can complement platform practice. But verify their format knowledge before committing — ask specifically about Redrock and the 2026 changes.

The candidates who perform best on Solve are those who practice actively, under timed conditions, with scenarios that match the actual game formats. How you get that practice — through DrillCase, coaching, or other tools — matters less than whether you get it at all. The worst strategy is going in with only case interview preparation and no Solve-specific practice.
