The value of practice is not memorizing scenarios. It is learning the mechanics, how information is presented, what decisions require, and how to manage your attention and time.

When the data changes, the underlying habits still transfer: compare options systematically, check calculations, identify relevant information, and avoid unnecessary rework.

Treat practice as training the process, not learning the answer key. If useful, this guide on McKinsey Solve guide gives more detail.

exact scenarios changing is why memorizing answers is pointless.

practice still helped me a lot with mechanics + not panicking.

McK prep is more about process than seeing same case again tbh.

I got a variation I never practiced and still felt prepared.

The interface familiarity alone was worth it for me.
