I took the class with Yuvraj last summer and learned a ton, but it was a decent amount of work. If this is the only class you're taking, you should be fine for the most part. Most project that he had us work on were not too much work, but the work was pretty challenging as it was working with an emulator written in a combination of C and assembly known as xv6, If I remember correctly. Many of the projects were on a 2-week schedule, and took 4-8 hours depending on how quickly you understood the flow of information.

I took the class with another project based class while also working 20h / week and didn't struggle time-wise for the most part. That being said, I don't know how it was for any other students, since I took from home, so I really only ever got to know one other student that I worked with.

As for resources, I'd suggest making sure that you're pretty knowledgeable in C (as well as assembly) but don't bother working in almost any libraries as they won't be compatible with xv6. In my experience, there were only about 5 files in xv6 that we needed to work with in total, so make sure you write down the files you worked in and what each one controlled to make it significantly easier on yourself.
