For students who arrive at a university without already knowing these opportunities exist, it's not always apparent that they do exist and may be available to them.
What people don't know is how good this stuff is, that they can actually get it done in parallel to the classes and how rewarding and educational it is.
This is definitely something where kids with parents who went to uni have a benefit, since they will know more about how to navigate the system and about things like this.
I didn't have this benefit, my parents never went to uni, but we had a lot of books and dad taught me to poke at everything :)
In fact, at my uni there is fear that going online will result in students deferring for a year, since undergraduate surveys are overwhelmingly in favor of in person class, to the point of not paying tuition for online offerings and extending their degree plan as a result.
