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.
Personal practice is free · about 15 minutes a case
Find what the answer cannot defend.
Your only supplier is preparing to replace you. Do you stay a distributor, launch your own brand, or wait?
“Launch our own brand because it gives us more control and more profit.”
What is missing? Pick every gap you notice.
- 01
Read the case
The case opens one stretch at a time: the next part appears once you send your answer.
- 02
Write your call
Choose a position and argue it in your own words — 20 words is enough to be rated.
- 03
Get it read back
A minute or two later: a score out of 100, what held up, what you missed. Keep reading — it finds you when it lands.
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.
- Focusnamed the real decision0–20
- Relevant evidenceused the facts in the case0–20
- Alternativesweighed the other options0–20
- Manage uncertaintypriced what you can’t know0–20
- Execute and learnactually 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.
