This class is not very hard, but there is a good amount of work you must put into it. Professor Reiher uses slides and reiterates with more clarity, but many people skip his 8 am lectures and instead go through his posted slides on their own. Midterm was 10 short answer questions while the final was 15, and both tests were very fair. The TAs go over the projects in discussion, and fortunately for me, I had very good TAs who went over the project specs in-depth. Though, some of my friends had a TA who wasn't very helpful, so I would switch ASAP to a better one if possible as it really cuts down your project time. Overall, your grade reflects the amount of effort you put into it. I'm not the smartest CS student, but I still managed to pull off a good grade. As long as you keep up with your readings (which many students don't), you should be good to go. This class has many important concepts, so you might as well put lots of attention to it.

CS111 requires tons of work. Reiher's tests are reasonable. If you spend enough time to study, it is manageable to get a good grade.

Professor Reiher is one of the most valuable professor in the CS department. I took both 111 and 118 with him, and even though from time to time the lectures could be a bit slow, his method of teaching these class adds valuable knowledge to your repository.

He mainly uses slides and explains them during lectures. Many people find this kind of boring which is understandable. If he could reduce the details a bit and use the blackboard from time to time it would be fantastic.

Like other people said, projects are entirely handled by TAs which is both good and bad. If you have a TA who is lost and really doesn't know their stuff, then good luck! Otherwise, you should be fine.

There was one midterm and one final. Midterm focused on details and concepts of OS and networking(in 118) and the final is about using those concepts to design something efficient that works. You might find it unconventional, but in my case that was actually very practical.

Overall, a very good professor and I recommend him.

Reiher relies 100% on his slides. His lectures can be boring, but he moves through material quickly and in depth. Reiher has no involvement with the projects at all, they are completely assigned, handled and graded by the TAs. The projects can be very time consuming, so it's important to work closely with your partner and go to office hours if you are unclear on implementation details.

Reiher's version of this class requires a lot of memorization of fine OS details, alongside fairly deep understanding required to pull concepts together to answer the long-form test questions. Open note final does help but the final is also brutal.
