USCF memberships are required for sections where the Rating Type is USCF.
If a section is both NWSRS + USCF rated, the USCF rating will be used for pairings.
Open sections are harder, U800 means "Under 800" and is the easier section.
Closed sections are by invitation only to the top rated players.
Scholastic tournaments with 5 rounds held between Sep-Apr are state qualifiers.
