Practice packs.
Curated pathways that pair the concepts you need with scored cases that put them to work. Each pack is an ordered sequence - learn the lens, then apply it in a real case interview - rather than a single activity to attempt in isolation.
Lead with the answer, turn observations into implications, and synthesize instead of summarize - then close two scored cases with a clear recommendation.
A tight final-round refresh - a structuring frame and answer-first delivery - then three advanced cases of different types as dress rehearsals.
Decompose growth into its drivers, then use Ansoff and BCG as lenses to choose where to invest - applied to three scored growth cases.
Master synergy logic and integration levers, then test them on three scored acquisition cases of rising difficulty.
Size the market, read the five forces, test the break-even, then make two scored market-entry decisions.
Build the profit-economics spine - contribution margin, unit economics, break-even - then use it on three scored cases.
Rebuild the arithmetic that trips candidates - percentage traps, weighted averages, growth rates - then prove it on three scored cases.
