You only see the meaning, then build the sentence yourself and say it. This is producing your own language, not repeating a memorised line.
How is this different from repeating after a model?
Repeating turns an existing sentence into sound. This makes you build the sentence itself — which is where most real conversations actually stall.
Is a different wording counted as wrong?
No. Any wording that gets the meaning across counts. The point is producing a sentence that works, not hitting one prescribed answer.
