Q: What’s the difference between CS50x’s “less comfortable” and “more comfortable” problems?
A: Some problem sets (i.e., programming assignments) offer problems for students less comfortable with computing and problems for students more comfortable with computing. Each week, you are welcome to do either or both!

Something not working? Problem set harder than you expected? Or do you simply want to connect with people from all over the world taking CS50’s courses? The best place for real-time Q&A (with humans!) is CS50’s Discord server at discord.gg/cs50. 👾

If you’ve finished one of CS50’s courses already, let us know your Discord username at cs50.edx.org/alum. We can give you an “alum role” so that when you answer questions, students know you might be able to help!

CS50’s own Duck Debugger (in pixel art!) wishes you a happy Valentine’s Day! 💘
