Her name is Katharine, but i put Katherine. Is this any sort of problem for me. I’m so close to her but it never occurred to me that she has one of those weirdly spelled names lol
If you misspelled it on a college application, I would not worry about it. If you misspelled it in an email or thank you note directed to her, just shoot her a quick email to apologize. No biggie. As a student, you are probably accustomed to addressing her by her last name, so even though you are close, it is an understandable error.
