Seems like a prof dependent course, but my prof made it chill. Basically didn't do any readings (30-40 pages each), except the parts that were needed for the 5 mandatory journals. It felt like 70% of the time was for presentations though, and the course seemed really unorganized.

A lot of discussion and talking about how we communicate to one another. I did like the course, but I felt like it could be so much better if it went more into depth about specific things rather than general everything.

Boring content. Difficult prof (Brian Lefresne). Tons of work. Good luck getting anything over an 80.

I think this class is very prof dependent. Try to get the section with Matt White and you'll love it. Readings were a bit boring though.

Prof dependant, other sections definitely were more difficult. Matt White was genuniely great though. Engaging, funny, very pleasant to talk to. He made the class a nice break from the rest of my day, something I would look forward to.
