I am applying for masters and I would like to know this as my professor has completely altered the phrasing of my paragraphs and also made a spelling mistake. I had to correct them, so the metadata shows that it was modified. Do they really check all of that, as it is otherwise a genuine letter?
Edit 1: I think I need to give more context. So in my university, the students are supposed to write their own letters of recommendation and approach the professor for signatures (they sign it if the mentioned skills and facts are true to their knowledge), as opposed to the professor writing the letter. I had sent my draft with good paragraph phrasing and devoid of spelling mistakes, and I got it back with the paragraphs jammed together (hence, the disruption of phrasing) and one spelling mistake. I have been having this ethical dilemma since my college is quite bad at communicating in general and if I need to get this corrected, I might not even be able to reach out to them as I am not a student at the university anymore (I graduated this year). I had to go through a lot of hassle just to obtain this letter and I don't want to commit any kind of fraud in any way.
Edit 2 : The letter has a spelling mistake where I have been addressed as the Proctor, when in actuality, it's my professor who's the proctor: I am the proctee.
Also, would a spelling mistake in the letter of recommendation affect my chances of admission in any way? Please do give me some insight on this, if anyone has any idea.
Edit 3: I would like to update that I have approached the professor to get this corrected, if possible. I will not be submitting the LoR that I made changes to. I really appreciate each and everyone who has given me frank and sound counsel regarding this ethical dilemma of mine. Thank you.
