Do I still have a chance at UPenn Nursing with this?

<p>I don't want to put on a full stats profile, but I am SO passionate about UPenn's nursing program. The thing is, my science grades have consistently been the lowest grades I have. (high B). But they were always honors classes and my high school is also very competetive. All of my other classes have good grades though. I can also write a pretty good essay and think I have good extra curriculars.
Long story short: I won't have a rec from a science teacher (World history and a really really good English teacher rec), and my science grades have consistently been low. Do I still have a chance at UPenn nursing?
Oh and my SAT is 1910</p>
