Can you help me understand the concept of "Professional Tuition and Fees"?

Take a look at this “Cost of Attendance” document, please.

Now, I am interested in an Undergraduate Architectural degree. I need help with these questions:

- Does an architectural student pay both the general tuition [3k], and the professional tuition [11k]?

- Why is an architectural degree so much more? Architecture has always been my love, and I’m frustrated that it costs more to attain.

- I read that a freshman does not have to pay those fees. When and what occurs so those fees must be paid?

I may have more questions as information flows in, so this is not a topic one should pop in and blurt a one liner answer – please and thank you.
