Do we have to take science if we go to Wharton?

<p>This is my first semester at Penn (I transferred up here). So, what if a student gets a D? Does that mean that student has to retake the course again or only if the student receives an F? Or is everything just based around a cumulative GPA (as long as someone maintains a 2.00)? Things are a little different than Texas up here, so I am trying to just get a clear picture of how it works (not that I will be getting any D’s)</p>
