Hey, I am a potential master's student in the field of chemical engineering Fall 2013. Recently I received admits from UPenn, CMU and Cornell(M.Eng). I am yet to hear back from the other colleges that I have applied to but I'm keeping my fingers crossed regarding that. My main query is that if it boils down to a choice between UPenn and CMU which would be the better option? On one hand Penn has a fabulous program tailored to what I want to do and wharton is another major plus point. The restriction on the various courses that one can take at wharton is a bit disappointing though. CMU on the other hand has a better ranked program but the tuition fee is pretty high. I'm leaning toward Penn but would appreciate a bit of advice regarding this decision of mine.
