Land your consulting offer.
CaseGrade is built for candidates targeting McKinsey, Bain, BCG, Deloitte, Accenture, EY, and the rest of the MBB + Big Four pipeline. The mobile app gives you drills, frameworks, and a practice system that adapts to your target firm and round — so your prep hours go where they move the needle.
What's inside
• Mental Math Drills — Timed arithmetic and percentage calculations. Build the reflexes case interviewers look for in the first 30 seconds of a quantitative question.
• Quantitative Case Math — Pricing, profitability, breakeven, NPV, and financial ratios. Each problem traces a realistic case setup; you practice the math that actually shows up in a BCG round two.
• Market Sizing — Structured estimation problems from top-of-funnel ("How many coffee cups are sold in Chicago per day?") through segmented market builds.
• Synthesis — Practice delivering CEO-ready recommendations, one-line answers, risk callouts, executive summaries, and key takeaways. The single weakest link for most candidates.
• Structures & Frameworks — Drill MECE issue trees on real case prompts. Build the muscle memory for a clean structure in the first 90 seconds.
• Brainstorming — Timed creative-ideation practice. A surprisingly common round-two sub-question that candidates rarely prepare for.
• Learn Section — Concepts, industry primers, and framework references you can open between drills or at the start of prep. Lightweight audio explainers on the go.
Adaptive practice
Set your target firms and interview date once. CaseGrade surfaces the content most relevant to how that firm actually interviews — and sequences it against your calendar so you ramp naturally toward round day.
Track your progress
• Daily streak and comeback-freeze so one missed day doesn't erase your momentum
• Percentile rank vs other candidates targeting the same firms
• Best-score history on every drill
• Skill report that flags the weak quadrant you should hit tomorrow
