<p>I'm applying to a few 2014 summer programs and was wondering how to ask for a rec letter? One of the teachers I plan to ask is a high school teacher (that has written me a rec letter before) so there's no problem there, but I worked with a professor in a lab this past summer and wanted to ask him for a rec letter. He said that he would write me one for college, so should I ask him for a letter for a summer program or would it be too much of a bother? If I should, will an email suffice?</p>
<p>Thanks in advance!</p>
