You’ve taken Christofides in 109, so there’s nothing new to expect. Somewhat dry lectures, that definitely make sense and a knowledgeable professor. That said, this class is, at it’s core, a math class masquerading as a ChemE class, and I personally found that Dr. Christofides was better at teaching 109 than 107.
——
While this class ostensibly teaches control systems, it doesn’t have many practical applications besides giving you a bunch of formulas to write down on a cheat sheet. Not much different from 109, but 109 was explicitly a math class. Probably my biggest gripe.
——
Exams were similar to 109. They were mostly about doing math problems quickly. Unlike 109, no conceptual questions were asked on them; for this class, you just need to know how to do the homework and you should be fine on the exams. Like in 109, old exams and homework solutions were amazing tools to help study. And speaking of Homework, it’s graded on completion. Most of the homework is short and manageable, and should only take 5 or so hours to do, with 4 in the entire quarter. Homework 4 was an exception, with a 32-page solution manual. I, however, did only 2/3rds of it and still got full credit, so…
——
Class grade distribution was 50% final, 30% midterm, 10% homework, and 10% final project. Homework is free points; the final and the midterm are where you’ll get an A or a B. I actually blew off the project, doing less than half of it and still got an A. Why? I did well on the midterm and final.
——
Other logistics notes: Professor clearly designed his lectures around being in-person. The recordings sucked, and the Zoom quality sucked too. For me personally, the lectures made sense when I was in his class, but I found that they really didn’t help with doing homework. Discussions were far more helpful when it came to completing homework.
——
There might/might not be a textbook in the store for this class, but regardless, Christo provides a PDF of it, with both homework problems and the actual textbook chapters for the homework.

Standard Christofides. You had him for 109 and he's the same. He's very clear. No nonsense. You'll learn the material well, but it may be dry at times. Overall, more interesting than 109.

Christofides is probably the best lecturer in the department. He genuinely cares about his students and whether they learn, and he's willing to adjust his pace to what his students need to succeed. I wish he taught more courses, he's just a great professor.

Echoing previous reviews, PDC is the same as from 109. He is entertaining at times. I would say the class is less dense than 109. Four homeworks, though the last homework was pretty long and I didn’t finish all of it. Exams are based off of the lectures and he gives practice exams which are helpful. The midterm was pretty decent; it seems the exam problems were arranged with the most difficult problems first. The final was almost exclusively focused on material we had learned in the last few weeks of class. TAs (Matthew Tom, Berkay Citmaci, Sungil Yun [whom you might recognize from 109]) are all very helpful. As an example, Matthew was very helpful in office hours and emails. He helped me with the project (which was about as long as the 109 project).

The TAs recommend using MATLAB/Simulink to construct Bode plots in the latter half of the course for homeworks and the project, so ask them to guide you through how to make them if you can’t get the programs to work.

The book is also concise and clear.
