Can someone help me correct these phrases?

Avant que j'ai choisi qu'école a laquelle...

I wanted to say 'Before I chose the school where....'

wow sorry about the many posts! My internet was just crazy

Avant, j’ai choisi l’école où...

Avant de choisir l'école où.....

Sra (aka Mme)

i don't know french that much but i think it should be Avant de choisir l'ecole ou , (like the others write it down)

To correct the phrase "Avant que j'ai choisi qu'école a laquelle...," you can make a few adjustments. First, you need to use the correct relative pronoun for "the school," which is "à laquelle" in this case. Second, you can rephrase the sentence to make it clearer and more grammatically correct. One possible correction could be:

"Avant que je choisisse l'école dans laquelle..."

This translates to "Before I chose the school in which..."
