Like any colleges, Penn has both pros and cons. As a graduate student in the School of Social Policy and Practice at Penn (Master's of Social Work), I find that the biggest strength of Penn is its wide reach of professional network, research, etc.
The amount of resources/networking opportunities available for developing insight, experience, and others is unimaginable here at Penn. Having deep connections with all three sectors of the non-profit, for-profit, and governmental world brings its students enormous opportunities and information/knowledge to learn and grow from.
The cons, however, is that Penn as a whole seems a bit lacking in terms of student activism and engagement. There are clubs to join. But, I rarely see them out in the quad or the walkway outreaching or being vocal about a variety of issues students are concerned with in this age and time.
