Hello!
To give you a bit of context, I’m a french student who applied to Harvard for the regular decision. I didn’t get an interview to exchange about various aspects of my personality and there are many things I wanted to highlight that was not mentioned in my application.
Could you proofread my mail, verifying all aspects, grammar errors, and punctuation, and if possible rewrite them with a concise and rich vocabulary?
Thank you in advance !!
