Independent BCG prep that respects your time.
CaseyPrep is an independent preparation platform for the BCG Online Assessment — Casey, the CCA, Pymetrics, and the Cognitive Test. It was built by ex-strategy consultants and engineers who watched too many strong candidates wash out at the online stage — not because they couldn't solve cases, but because the format surprised them.
Who builds CaseyPrep
The core team pairs ex-strategy consultants (BCG, McKinsey, Bain alumni) with product engineers. Consultants own the case content and scoring rubrics; engineers own the simulator, timers, and AI evaluation stack. Every simulator ships only after both sides sign off.
Our methodology
We track BCG's assessment formats actively across offices and regions. Each pillar guide and simulator is calibrated against three sources:
- Publicly available test-taker reports — post-mortems, forum threads, and firsthand write-ups from recent candidates.
- Ex-recruiter and ex-consultant input — structured interviews with people who have seen scoring dashboards or ran candidate pipelines.
- Internal benchmarking — we score our own simulators on the same rubrics we publish, and track candidate progression through the funnel over cohorts.
Every guide has a "Last updated" date. When BCG rotates formats — Casey to CCA in a region, Pymetrics adjustments — we review affected guides within days, not months.
Independence
CaseyPrep has no affiliation with, endorsement from, or authorization by Boston Consulting Group. We do not use BCG's questions, exhibits, or branding. Every simulator is original content modelled on the published structure of BCG's assessments — the same information any prospective candidate could compile from BCG's careers pages and public write-ups. Trademarks belong to their respective owners.
Free-tier commitment
Our free tier exists so prep doesn't depend on ability to pay. Sample Casey cases, mental-math drills, and the full library of guides and glossary entries are always free. Paid plans exist to fund the platform and to unlock the deeper simulator library — not to gate the basics.
