I took CS6300 - Software Development Processes and CS7641 - Machine Learning. I would not recommend two classes at once in your first semester, and never two classes with ML. (I've heard that Networking is comparable to SDP, and advanced operating systems is comparable to ML.) SDP required 9-12 hours a week on average (many more some weeks) spent on group projects. It would have been less if I'd been working alone. The hardest part is working in a distributed team with no leader - especially because lots of people take this as an "easy" intro course; of the 6 people I worked with, 4 of them were not comfortable being asked to do any programming. O_o ML required ~25 hours a week on average; I spent close to 100 hours on it during weeks with projects due - fortunately there are only 3 projects. The lectures are longer than SDP, the projects are hard, and there are exams that you'll have no idea how to prepare for. You will love it anyway.
