What you get — assessment specs

Three simulation modules covering every consulting assessment task. Built from the ground up with realistic interface, timing, and question style.

Data Analysis Simulation

10 data analysis scenarios — Ecotopia, Costa Thales, Kokona Falli, and 7 more. Each with unique datasets, exhibits, 4 analysis questions, and a research journal. 35 min timed.

Systems Thinking & Decision Modeling

11 ecosystem scenarios total — Sea Wolf (Ocean Cleanup) + 10 Decision Modeling Lab scenarios covering urban air, wetland, forest, mangrove, and more. ~25 min each.

Built-in Calculator & Research Journal

Research Journal with drag-to-save, built-in calculator, and multi-exhibit navigation — the same on-screen tools as the actual assessment. No switching tabs, no external tools needed.

Two plans. Both cheaper than one hour of coaching.

Pay once, prepare thoroughly. Both plans cost less than a single coaching session — and you can practice as many times as you need.

Things People Ask

Is this based on real consulting firm assessments?add

Our simulations are original content built by our research team, inspired by the data analysis assessment format used at top strategy firms. We studied hundreds of documented assessment experiences to reconstruct the format, question types, time limits, and interface as accurately as possible. You get the closest possible preparation using original, independently created content.

Which modules are included?add

All three training modules: Data Analysis Module (10 data analysis scenarios — Ecotopia, Costa Thales, Kokona Falli, Bali Village, Isla Azul, Zahari Plains, Selva Nova, Cedarburn Ridge, Purple Line, Nolotiles), Systems Thinking Module (1 scenario — Ocean Cleanup), and Decision Modeling Lab (10 decision scenarios — Urban Air Quality Improvement, Wetland Restoration, Forest Biodiversity Restoration, and 7 more). VIP customers also get the legacy Ecosystem Optimization simulation (Coral Reef + Mountain Ridge), a legacy module useful for additional practice.

Is it timed like the actual assessment?add

Yes. Each simulation runs on the same time limits — 35 minutes for data analysis, approximately 25 minutes for systems thinking and decision modeling. Data analysis follows a 3-phase flow: Study phase (investigation, objective, study info, exhibits), Analysis phase (4 quantitative questions with review), and Report phase (written report + graph selection for your visual report). There is no pause option during a session.

What's new in the latest update?add

We replaced the Ecosystem Optimization module with the Decision Modeling Lab as the third training module. The new module features 10 decision scenarios — urban air quality, wetland restoration, forest biodiversity, coastal mangrove restoration, and more — instead of the food chain building mechanics of its predecessor. Data Analysis now includes 10 scenarios with updated themes. Systems Thinking remains the ecosystem optimization module with its Ocean Cleanup scenario and drag-and-drop mechanics.

What is the refund policy?add

VIP lifetime: 7-day money-back guarantee, full refund with no questions asked — even if you have completed every scenario. Basic 1-year: no refunds. At $99, it is less than half a typical coaching hour, and you keep access for a full year.

How is this different from other consulting assessment prep?add

Most resources give you walkthroughs, tips, or static practice problems. We built interactive simulations that recreate a realistic assessment interface — multi-exhibit navigation, a built-in calculator, and a Research Journal with drag-to-save for capturing key data points. You complete the full flow: study phase, analysis phase (4 quantitative questions), and report phase (written report + graph selection). Our detailed performance review tells you exactly where you lost points and why. 21 scenarios across all modules, unlimited retakes, no scheduling, fraction of the cost of a coach.
