Short, timed drills for each part of a case interview, graded the moment you answer, with a worked solution every time. A free account gets 5 drills a day.
Case maths under time pressure: profitability, breakeven, investment and ROI, payback, margins, growth and CAGR, a simple DCF, capacity, unit economics, pricing and expected value. Each topic comes as a pure calculation, a numeric mini-case or a question read from a chart.
Build an estimate step by step from your own assumptions, or spot the one assumption that is out of range.
Pick the structure that fits the brief, fill in a framework, or build a structure in one minute, for profitability, market entry, M&A, growth, pricing and operations cases.
Read the exhibit fast: tick the insights a chart supports, or read off the numbers and compute. Bars, waterfalls, Marimekko charts, financial statements, Sankey diagrams and more.
Generate ideas against the clock for growing revenue, cutting costs, why a number moved and what could go wrong, then compare them with a model answer sorted into buckets.
Drills sit alongside the full cases on Case Ace and the free mental maths trainer. New to cases? Start with what a case interview is.
