Letter of recommendation from last year

<p>I asked my history teacher to prepare a letter of recommendation for me at the end of last year. It includes things like “Andy is a student in my class this year”… and “Andy is awaiting AP Scores for his [insert list of tests here]”… Well, I have those scores I’m no longer in his class obviously. </p>

<p>Anyways, I sent him to invitation to fill out the common app. He told me he just attached this letter from last year.</p>

<p>It is dated as May 17, 2011.</p>

<p>Will the admissions people be confused and see this as some sort of red flag, or will they understand that the letter is from last year and not hold it against me?</p>
