👇 Why he studies and forgets

Sunday evening, at home

He studied for two hours. He got 8.

Sunday, 5 p.m. He has been studying his history test for two hours — you saw him do it, he wasn’t cheating, the phone was in the other room.

Tuesday, he comes home with an 8. “I had learned everything. In front of the paper, I forgot everything.”

And you don’t know what to say to him, because you know he’s telling the truth.

The real reason

The problem isn’t him — it’s the method

Between CM2 (10-11 years old) and 3e (14-15 years old), the amount to remember triples. The method, however, has stayed the same: reread, underline, reread again.

Rereading gives the feeling of knowing — you recognize the lesson, so you believe you know it. But recognizing is not remembering. On test day, there is no page in front of you.

What he lacks is not revision time. It’s a hook per concept — something that comes up on its own, even under pressure.

You have surely already tried

And you were right — but none of them solve this

Making him reread his lessons

That’s what he was taught to do. Except rereading reinforces the impression of knowing, not memory.

Private tutoring

Several tens of euros per hour. It saves the current chapter, not the way to learn the next fifty.

Making him copy notes

Hours of copying, and a sheet he will never reopen. The effort is real, the trace is not.

This book does not replace any of the three. It does what none of them do: give each concept in the program a grip to hold on to.

What's inside

A trick, and it’s remembered until the Brevet

Dozens of concrete tips that stay in the mind forever, in all subjects:

📐 Pythagoras & Thales
The 2 theorems that appear on every test — finally clear.
📏 SOHCAHTOA
Trigonometry without stress: sine, cosine, tangent all at once.
📖 Figures of speech
Métaphore, hyperbole, oxymore… never confuse them again.
⚗️ Physics-Chemistry & Life and Earth Sciences
Formulas, elements, key cycles — remembered for the Brevet.
MathFrenchPhysics-ChemistrySVT (Life and Earth Sciences)History-GeographyTechnologyEnglishSpanishArts
And then, this happens

The day he leaves the test without a blank mind

He had confused Thales and Pythagoras since 4e (13-14 years old). You show him the trick that separates them — three seconds, a silly image, impossible to mix up afterwards.

The following month, right in the test, he no longer searches: the image comes back before the formula.

That’s all we aim for: that he stops revising more, and starts remembering better.

Two ways to get it

The same book, you choose when

The 145 tricks are identical in both. The only question: is he revising this weekend, or do you want to give him a real book?
