Delivering Software: From Concept to Client
This is one of the best electives I have taken at Duke, hands down. This is because the skill sets you practice is this class are very practical and are applicable to real-world situations which you don't get from a lot of CS classes in general. Also, there were catered dinners every class in my semester (Fall 2019).
This is one of those hidden gems in the cs department. First off, you work with a team on a real project (great for your resume). Second, it is really really easy. Just do what the client says and you get an A.
