I have taken two different GS 185 classes with professor Sengul and I would gladly take more!
She is absolutely brilliant, but I've found this is part of why people find her confusing. She asks the class complex, abstract, and philosophical questions that can sometimes be hard to fully comprehend without dissecting each part of the question. While the questions she poses may be challenging she really doesn't ask very much from people and her assignments are not any more challenging than other GS classes. She assigns interesting readings, she uses slides, and she is extremely kind, accommodating, and helpful! In my experience, she enjoys talking with students and is happy to help. She is so passionate about what she teaches and you can tell she really wants students to succeed.

DO NOT TAKE
I had to stay in the class because literally everything else was full I checked every department to get out of this class but nothing was open.
She will shut you down if you ask questions, she has too many thoughts going on and tries to explain them all at once and you are left just wondering what she is talking about. I literally could not understand what she was saying it was so frustrating. Take this class if you are ready to teach yourself everything and the readings she assigns are heavy and LONG.
Avoid if you can
