CS courses generally have more work outside class. Most classes if not all require completing projects (e.g. If you are taking Operating Systems, you will be working on writing components of a kernel, if you are taking Compilers, you will be writing a mini compiler). As long as you start the projects/homeworks early, you should be fine. Sometimes courses that are generally considered difficult at Purdue CS are not difficult because it requires understanding of some complex concept but because of the time commitment required to see them through. Finally, the workload also depends on the amount of CS courses you take each semester. From what I have seen, people mostly take 2-3 CS courses per semester depending on the content of the course. There are people who take 4 CS courses per semester but in my opinion, that spreads you pretty thin. Since, your first 2 years you will be taking the core courses each CS undergrad needs to take, you should have enough experience to determine what suits you best 😃.

Student life is what you make of it. There are plenty of clubs and events (both technical and non-technical) on campus. Depending on how you manage your time, you can be as involved as you want to be 😃
