Easy Elective CSCI Classes?

I’m going to graduate next fall, and Im looking at which classes to take. Im planning on taking CSCI 4707 (database systems) as one of my classes. I would just take that class, as it’s all I need to graduate, but looking at cost per credit, it will end up being cheaper for me to take 13 credits than for me to take fewer. Does anyone know of easy CSCI electives? I’d prefer to take something that might be applicable in the future rather than just taking some random lib-ed course just because I have to take it.
