the fraternity rankings at sdsu

Underground Fraternities/Secret Societies
1) Psi Upsilon - Probably the most wealthiest of SDSU students and/or the very "promising" ones. Small groups are selected. Were very selective with their Brothers and were incredibly secretive. Probably closest thing to a underground fraternity - not completely a full blown secret society.
2) Sword and Key - By far the most secretive. Selects their members from all classes. Very strict with their members in regards to membership exposure. Definitely a secret society.
