I'm not sure about 'permanent'. It's a perm which I think is actually short for 'permanent wave' - you wouldn't ask a hairdresser for a permanent surely!
There must be a better definition of quad. A four wheeled motorcycle perhaps, or one of four in a multiple birth. The only word I know for a campus courtyard is agora.
This may be a regional/cultural difference. "Quad" is a common standard term for a campus courtyard in US colleges, or at least all the ones I've ever known, while I've never heard anything outside of ancient Greece called an agora.
