Overview
A full case, led the way a real interviewer would.
Pick any case from the library. Case Ace opens with the case prompt, then takes you question by question — structuring first, then the numbers, judgement calls and synthesis. When you ask for data, the relevant exhibit appears. When your structure wobbles, the interviewer nudges you back — exactly like the real thing.
At the end you get per-question marks on structure and commercial judgement, plus a written report from the same feedback engine that powers our other sims.
