Ronna was by far my favorite professor first semester. She's knowledgable, sweet, and just an overall good person and professor. She made everyone in the class feel comfortable and was able to facilitate group discussions really well. Her office hours are also really helpful, so be sure to go to them. She tries to make herself available as much as she can.
She grades fairly, and is very conscious about handing drafts back so that we have enough time for the final draft. My advice would be to treat every draft like the final draft, so that you don't have to cram writing a whole new essay in a week.
The readings she chose were really interesting too, more so than the other sections from what I could gather. They changed my views on a lot of different gender related topics.
Bottom line: if you're placed in Ronna's class, be thankful. If you take Uwriting second semester, then try and register for her class. You won't regret it!
