<p>I know this seems like a lame question, but...</p>
<p>Many summer programs require a letter of recomendation (or two) from your teachers. Assuming you are applying for more than one, is it ok to use the same recomendations?</p>
<p>It would be expected. Try to give them to the teacher at the same time so that it is easier for the teacher. The teachers will mail them to the summer program directly or give it to you in a sealed envelope that you will include in the application packet.</p>
