Oh yeah, I can just imagine a line of people wanting to learn Strength of Materials course for fun, or anything equally crazy (requiring at the same time fresh knowledge of other hard uni courses as a prerequisite, a lot of strict rigor in studying and just pure baseline intellect to get it at all). One can learn Latin for fun, starting from literally zero and stop any arbitrary level too. One can't learn ANY hard STEP topic without doing that continuously on a progression. If god forbid you take a gap in studying STEM courses, in a decade you will have to restart from school program again :) .

PS: I get all the idealistic mulling about how universities should be these utopian centers for the voluntary knowledge study and collaboration and the only result should be merit based. But real world doesn't work like that. If a country wants to have professional chemists or say welders for example, it must force kids through a lot of boring and hard mandatory study for years. Humanity didn't invent anything better yet, sorry.
