Cert prep takes ages. Kevin is counting on it.
- Weeks of study to squeeze in between work and everything else.
- Hundreds of questions, on your own, with no idea if you're actually getting anywhere.
- One evening off, then two. And exam day comes anyway.
Three minutes a day. Gérard handles the rest.
One session, three minutes
Eight questions, an explanation after every answer. Fits in a tram ride.
You know where you stand
The readiness gauge tracks your prep domain by domain, weighted like the official exam. Gérard gets promoted along with it.
Your mistakes come back
Spaced repetition serves each question again just before you'd forget it. The ones you miss come back before the session ends.

Gérard's story
Street pigeon, unimpressed, secretly ambitious. To become a carrier pigeon, he needs a certification. Just like you.
Chapter 1
Meet Gérard.
Street pigeon. Specialty: fries dropped on the pavement. Ambition: none. Until that morning.
Chapter 2
The carrier pigeons.
Uniforms, medals, respect. They carry the important messages. Gérard carries a fry.
Chapter 3
The problem.
To become a carrier pigeon, you need a certification. Gérard has never studied in his life. He panics. A little. A lot.
Chapter 4
And then there's Kevin.
The neighbourhood seagull. He steals fries. And the study streaks of anyone who gives up.
Chapter 5
He needs a study buddy.
You're preparing your certification, he's preparing his. Every day of study earns him a promotion. If you give up, Kevin wins.
Gérard is wearing: Mail carrier cap
Official. Almost.
