My professor sent me a copy of my LOR, I didn't ask him to but he did anyway. In the very first sentence he mispelled my last name, put an R instead of L. I don't know how noticable it is, except to me, but I do have an uncommon last name. He knows me really well and it was just a simple typo. But do you think it might hurt me or look bad, or will law schools not notice.
