Questions before you buy

No. DrillCase is an independent practice platform. It is not affiliated with, endorsed by or connected to McKinsey, BCG or Bain. The practice material is written by our team to match the publicly described format of each test; no real test questions are used.

We copy the format: the chat-led case with exhibits and a countdown for BCG Casey, the game-based tasks for McKinsey Solve, and timed multiple-choice sections for Bain. We cannot copy the real questions or the firms' own scoring, so treat your DrillCase score as practice feedback, not a prediction of your result.

29 BCG Casey-style cases with 275 questions, 23 McKinsey Solve-style scenarios, 476 Bain-style aptitude questions in 23 timed sets plus 3 mock tests, a free library of 63 case studies and 582 free drill questions. Counted on 2026-09-23.

No. You pay once. Casey Complete and Ultimate, McKinsey VIP, Bain Comprehensive and the All-Access Pass are lifetime access; Casey Starter, McKinsey Basic, single Bain modules and the mock tests give 1-year access. Prices run from $20 for one Bain module to $350 for every BCG case.

Yes. One full BCG Casey-style case and one McKinsey Solve-style scenario run free, with no card and no account. So do the library of 63 case studies and 582 drill questions.
