Being a good writer generally doesn't matter in high school. Most classes don't require much writing and for those that do, they just require students to convey the right number of facts and avoid most grammar mistakes.
Kids also engage in far more code-switching than adults, I think. When asked for a recommendation, It's possible that this particular kid just dashed off a quick email rather than really sit down to write something engaging.
But seriously, if I were doing a Y Combinator application, I would make sure that my testimonials were spot on. I would do so because one of Y Combinators' most enduring bits of advice is 'build something people want.'
I'd even equate that to grammatical errors in a website. You're competing for an interview against thousands of the best minds around. Proofread your copy!
Rather, I'm saying that when you apply to Y Combinator, you are competing against the best entrepreneurs around for a very limited number of seats. Since Y Combinator is so competitive, your chances of getting in would be better if you started working with a good writer or editor.
"I was accepted at Yale. Julia of Mentr was amazingly helpful and guided me all along the way. I'm so thankful her who helped me with my essays and got me to this point."
Obviously fake testimonials and stock photos are major red flags. If you have to use fake testimonials, for the love of all that is holy, find a good writer.
