I don't have much to say about Demiroglu. She taught the material adequately, homework assignments don't take much time to complete, exams are fair. Though, I will say that the midterms felt a decent amount easier than the final, which was both LONG and had more difficult problems, so be prepared for that. I never went to discussion because my TA went on tangents teaching us higher level concepts we didn't need to know, but even so I did well in the class just by reading the textbook closely.
