Need advice on writing a strong Letter of Motivation for Paris-Saclay University

Hey everyone,
I’m applying to a program at Université Paris-Saclay, and I’m struggling a bit with how to write a strong and convincing Letter of Motivation.

I’ve checked the official guidelines, but they’re pretty broad. I want to make sure my letter actually stands out and fits what Paris-Saclay looks for.

If anyone has applied there before (or has general admissions experience), I’d love advice on:

• How to structure the letter for Paris-Saclay
• How much emphasis to put on academics vs. personal story
• What parts of your background matter most to highlight
• Common mistakes applicants make
• Any tips to make the letter feel genuine and not cliché

Any guidance or examples would really help. Thanks!
