Not too easy. Not too difficult.
The Professor is quite possibly the best teacher I have had at Northwestern. Her enthusiasm, caring and teaching style makes your time as a student worthwhile and enjoyable. Many Professors have an incredible grasp on their class material, and Sara does as well, but she is able to communicate that in a way that is really accessible for students. Above and beyond all this, she is always willing to help outside of class hours. As far as material, its not super interesting, but definitely a good introduction to computer science, and valuable for the future.
Highlights: the professor, and the TAs who are readily available for office hours.

Advice for students:
Start weekly assignments early and go to office hours, especially Sara's. Also, follow her advice and play around with the code from the lectures, it definitely helps.
