I remember literally the only way to get a spot reserved in some /mandatory/ courses was to find an upper classman with prioritized registration dates and a free schedule to hold the class for you. In you're in a frat, great. If you're a bit of an introvert that lives off campus, you're shit out of luck.
I imagine UW is fully aware of this, I cant believe that it's still so much an issue that they felt the jeed to expell you for even having the gall to demo an idea. Absolutely appalling
