The transition from drills to full cases is a separate skill. You need to practice deciding which skill to use next, not just performing each skill in isolation.

Keep targeted drills for weak areas, but add full cases where you deliberately connect the sequence: clarify the objective, structure, analyze, calculate, interpret, brainstorm when needed, and synthesize.

After each case, identify the first point where your process broke down. That is usually more useful than reviewing every small mistake equally.

A good weekly rhythm mixes focused drills with live full cases and review. This CaseBasix MBB case interview prep guide can help you organize the skills into one end-to-end process. See MBB case interview prep.
