Awesome, really. I think this semester was her first time teaching a UW class, and she couldn't have done a better job. Emily is one of the nicest, most enthusiastic UW professors you could possibly meet on campus. At times, you feel slightly overwhelmed by her earnestness, but it becomes something you grow to appreciate once you're in the midst of papers/midterms/etc. She is lenient on deadlines and understanding of whatever situations may arise, which may cause people to slack off on turning in drafts (or quality ones, for that matter) -- but it's honestly to your advantage to give her your best work, regardless if it's a draft or not, because she takes the time to read through (and INCREDIBLY thoroughly) anything you give her. Literally, she spends a good half hour or more reading, commenting, and critiquing all of it... AND she'll even include a letter at the end that fully explains her questions and concerns, and suggestions for improvement.
I'm pretty sure a majority of the students enjoyed the class, and the entire class appreciated the fact that she wasn't an uppity, condescending professor whose 75 minute session is one of those classes you dread. She goes on tangents sometimes, and tends to get off-track, but it doesn't really prove detrimental to the class, overall. The readings are a bit tedious sometimes, but interesting; she knows them inside and out.
All in all, she's a great prof. You'll be lucky to have her teach UW.
