💡 The secret of good students
What is a memory aid?
A little trick — a funny sentence, an image, a gesture — that makes a difficult lesson enter the mind… and prevents it from leaving. Proof: you still remember those from your childhood!
😮💨 On homework evenings, you know by heart
The 9 times table that won’t stick. The “a” and “à” confused for the hundredth time. Tomorrow’s test that stresses the whole house. And that little phrase that tightens the heart: “Anyway, I’m useless.”
💡 The trigger: their memory works very well
Ask them the lyrics of their favorite song: they know everything! The brain remembers what is funny, visual, rhythmic — and forgets the rest. The memory aid turns every lesson into something impossible to forget. Proof: “Ornicar,” you still know it.

"But where is Ornicar then?"
Mais, ou, et, donc, or, ni, car: the 7 conjunctions hidden in a sentence impossible to forget.

The Order of the Planets
"Here I Am All Wet, I Am a Swimmer"
Mercury, Venus, Earth, Mars... the first letter of each word gives the planet. Magical.
Tips, Subject by Subject

✍️ French and spelling
The homophones that trap everyone (a / à, et / est, ces / ses), past participle agreement, the subjunctive, literary figures and literary movements. Fromelementary to high school, each rule has its short formula to remember.
🌍 History, Geography and Science
The order of the planets of the solar system, the rivers of France, key dates, civic education education. Then physics-chemistry and the SVT (Life and Earth Sciences) : Ohm's law, the periodic table, DNA, mitosis and meiosis — chemistry also has its mnemonic devices.
