SOLVED. Help find this book : Boy who has to take an exam (sensory machines to test capicity?) to determine a score? in the future? *involves the government* [s]

I see an image of this boy talking to his grandparents on a video-call type machine?
Him going to this place with lots of other kids to take this test
I didn't finish the book so i can't give too much details...
>might be a french book<

Edit : The kids thought it was a test but they were in fact brainwashing them to put them in different spheres

Found it! it was Linus Hoppe

I'm still not able to choose the book so that I can add it to our shelves. Is this only my problem?

And now it works. Go figure.
