How it works
Read a real business case. It stops where the company had to decide. You make the call, say why, and get your reasoning scored against the case.

The case is the lesson
Each question sits beside the evidence that makes the decision worth debating.
Take a position in your own words. The review looks at how you frame the problem, use evidence, compare alternatives, manage uncertainty and commit.
How your answer is scored
A reviewer reads the case and your answer. It scores five things out of 20 each. Added up, that’s your rating out of 100.
- Framingnamed the real decision0–20
- Evidenceused the facts in the case0–20
- Alternativesweighed the other options0–20
- Uncertaintypriced what you can’t know0–20
- Commitmentactually chose, and said why0–20
Being right isn’t the test
Matching what the company did earns nothing on its own. A well-argued disagreement can score higher than a lucky guess.
Nothing is locked
Every answer stays editable forever. Change it and ask to be rated again — a low score blocks nothing.
Cases count equally
A case scores the average of your answers in it. Your overall rating averages cases, so a long case can’t outweigh a short one.
