I think the we want to know you goes both ways. The college holds the power. So they want to know you and can use the info as they see fit.
My son wrote about being literal and used an anecdote about Sheldon Cooper from Big Bang. He’s not on any spectrum. Just how his mind is.
I was fearful of the essay but he just talked about how he focuses more on what his friends say or delays a response to cope and ensure he’s not missing the joke.
It worries me. He did real well admission wise.
My issue in OPs situation is they are using it to justify 3 Bs. Perhaps the student simply earned a B.
That’s not a crime.
