<p>My son attended A university's summer program and got a very good
evaluation letter.</p>

<p>He's sending an original letter to the A university as a kind of addtional
letter of recommedation and thinking about sending copies of the letter
to other Ivies. If the other Ivies know that they received the copy,
not the original, is it againt him or don't care about it or consider it
based on the evaluation ?</p>

<p>If it is againt him, as they believe that the original letter was sent to A University and they got a copy, should him not to send the copy version ?</p>
