So during registration I saw that I can change courses that were pre registered. So I tried to change them by making sure they fit within my schedule and that they don’t conflict and also that they have seats. However I couldn’t because the registration said that no schedule configuration is available using selected courses. I saw others managed to. Why can’t I? My registration is still active

So my registration is in like 7 hours and I have to select between world views and knowledge for my general ed course. However I’m kinda confused on what I do in those courses and I wanna ask if y’all know the difference between those two things and what courses I can take for those two and where I can find a list of them and also what I can like expect from each.
