There are three semesters. The fall and spring semester studio both concern large-scale architectural issues of urbanism and landscape/nature. The summer semester is thesis where the focus is entirely up to you. There are many fantastic seminar courses to choose from, which are also flexible according to what each graduate student wants to investigate/produce in terms of projects / papers / drawings and so on. Again, it's a post-professional degree program, meaning students are free to explore without the constraints of NAAB. And of course, you get to study within the creatively and intellectually rich environment of Cooper. If your idea of architecture is that "architecture = a building" then this program is either not for you, or, this program would provide exactly what is lacking from your education up to this moment.

It is not uncommon for architecture programs to contain design at an urban scale, some push this more than others.

On the other hand, most urban planning programs I have seen are less focused on the experience and more focused on research and bureaucratic elements involved with the design at that scale.
