True, but it still surprises me that a lot of universities have enrollment caps. If you want to be present for a live lecture, in-person or telecast, then you should pay a premium. Otherwise you should be able to take online courses in the style of Udemy and sit in for proctored exams.
If you can keep these from being multipurpose then name them what they’re for. If they’re multipurpose then just name them something totally unrelated. I name apps at work occasionally and if you try to get specific (e.g. network-configurator) you pretty much doom yourself to start using it for something that doesn’t match the name.
