<p>I asked my research mentor to write me a recommendation letter because I have been working with him for several years. He recently sent it to me (unsolicited) and I noticed that he said I am "preparing to take AP Physics B" when in fact (as my transcript shows) I took it two years ago. Is this something I should bother trying to contact admissions about? The letter has already been sent to almost every school. It seems minor, but I thought I would check here.</p>
