It could also work for much of Europe, but we probably wouldn't use the word "sophomore", and I've never seen or heard of a school with no windows. I doubt it is allowed.
(For example, the UK requirements for a school building state "giving priority to daylight in all teaching spaces, circulation, staff offices and social
areas" and "providing adequate views to the outside or into the distance to ensure visual comfort and help avoid eye strain" [1])
The shortest day in San Francisco is 9.5 hours. The shortest day in Chicago is slightly north of 9 hours. The shortest day in London is less than 8 hours.
That's not an insane schedule. It's a bit longer than regular day, unless you're in London or north.
Is it possible that you were really really tired? That schedule sounds insane to me. Unless you're very high north, I guess.
