You can get up to Bowman classification shooting at your club that's how a lot of archers do it. Your club monitors and calculates your annual handicap and indoors all classifications and handicaps can be obtained shooting at your club.
Some archers like to only count scores shot at competitions as they believe these reflect their true ability that's their choice but until you are shooting MB and above there is no obligation to do this.
