I got segregation out of that.

Not a fan, but sometimes it’s necessary. In public school foals are segregated by species at some point to learn about their specific racial differences.

Unicorn about magic.

Pegasus about flying.

Earth ponies about nature, and advanced physical education.

In college, you can take classes on the other subjects as a humanities credit. Kind of weird if you’re a Unicorn or a Pegasus getting a humanities credit for P.E.
