<p>So, I have asked my principal, my teacher of math and my teacher of physics to write a recommendation letter for undergraduate admission.
But I was searching the Internet and I read that one of the letters should be from a non-science teacher (kind of history or geography or foreign language???)</p>
<p>Do I have to ask another teacher for a rec. letter?</p>
<p>P.S: I want to study computer science. I am applying at Dickinson College, Connecticut College etc...</p>
<p>Thank you</p>
