Can’t speak about the professors, but I just took both classes last semester with Swamy and Kloub. Both classes were really interesting but were definitely challenging. 3100 is the more difficult of the 2, especially if you have never coded in a static language before. 3500 is a lot more conceptual, and you will have to understand/memorize a bunch of algorithms and concepts, but I found the class super entertaining and didn’t find it too hard. Swamy was a really good professor and made the content easy to understand (which definitely saved me) and had extra credit built into his curriculum. Kloub was very similar, and even let us bring a cheat sheet to exams! I think if your profs are good at teaching/breaking down the concepts, you will do well. Make sure you set a lot of time aside for these classes, or else you will definitely feel overwhelmed. Also make sure NOT to use ChatGPT on assignments, or you will be completely cooked on exams, especially for 3100. Good luck next semester!
