<p>I know UPenn needs 2 recs but does it have to be 1 math/sci and 1 humanities or can it be from 2 math/sci teachers?</p>
<p>they don't specify, so it shouldn't matter really</p>
<p>they prefer that the teachers be of subjects in which you have major interest in studying at penn, or that you have studied well & extensively in during high school.</p>
