Question 3Vous avez répondu D · la bonne était C

Find the odd one out in this list.

La 3e ligne porte un D en 3e position là où les autres ont un C. Balayer les quatre lignes à la même hauteur plutôt que de les lire l’une après l’autre : une différence se voit à la colonne, pas à la ligne.

FAQ

Frequently asked questions

Do the exercises really match the CSO tests?

The formats, question counts and durations match the sections sat at the Centre de Sélection et d’Orientation. The questions themselves are written for this platform: reproducing the official papers would be illegal, and pointless since they change.

Can I really practise for free?

Yes. The free account opens every available test, at 1 session timed session a day, with no card required. Once the day’s session is done, you wait until tomorrow — Premium lifts the limit.

What happens if I close the page mid-session?

Your progress is saved automatically. When you sign back in, a button offers to pick up where you left off, with the remaining time recalculated on the server.

Can I use it on my phone?

Yes. The site installs as an app from your browser and keeps working offline during a session already under way.

How do I cancel my subscription?

From your account, in one click, at any time. Premium access stays active until the end of the period already paid for, with no renewal.

Is this service official?

No. This is an independent practice platform, unaffiliated with the French Ministry of the Armed Forces or the Army. It issues no official document and guarantees no selection outcome.
